You really are overly obsessed with this Manni.
Well you get an MMR penalty for queueing with friends, it gets worse as team size gets bigger. The front page of games is nearly guaranteed to be teams of 4 or 5. It's always nice, for me, to solo queue and see 450 spectators notification pop up and know that I just rolled my way into some annoying miniskrim.
If you have a team of 5 you don't have to be the best players to get the top page, but your MMR would still have to be reasonably high. Theoretically that means you are at least decent, if you see bad play in a top game it's more likely the person is just screwing around, in my opinion. I've definitely been in 800 spectator games where my entire team randomed and got four carries so SF decided to go aura/stats and buy support items/etc.
Most of my games someone on either team is just absolutely horrid and does not deserve to be in the game with the rest of us, that tends to be how matchmaking balances games. In my experience with page 1 games, though, there is rarely someone who just flat out doesn't fit skill wise. At least, more rare than page 2-10 games.
I've seen evenly matched games but I've also seen a lot of games where there was a Leoric who skilled aura and crit before stun and built Sange and Yasha, or a Clockwerk that did nothing but feed and talked shit all game. I guess it's possible these types are just having a bad game, but it most of the time it seems like the mistakes and errors they're making aren't due to just a momentary lapse in judgement.
In HoN everything that had to do with MMR was visible, and when you went from the 1800 or 1900 rated games to your smurf account to play with your 1600 rated friend you'd see games full of people telling you about how MM is broken and rating doesn't mean anything and saying how even after 1500 games they were still 1600-rated only because their teammates were always bad. And I used to stomp with Juggernaut mid rushing blink dagger and aghanims every game at 80-90% winrate, something I couldn't do and get away with on my main account but hey, MMR didn't mean shit.
The fact that the numbers aren't there just makes people disillusioned as hell in dota 2. There was an interview with Eric Johnson in TI2 where he said he constantly gets email from people asking him to up their rating because they're always better than their teammates. He'd do that, upping them from say the 40th percentile up to the 60th and then he'd check back in a few weeks and they'd almost always be back right where they were before he upped their ratings.
Can I email him and ask him to lower mine? I'm really tired of the massive tryhard at my MMR level and the fact that I can't play with ANY of my friends because the people we get matched with will flat out facestomp them. That's probably my biggest complaint, I guess. One player doing well is NOT equal to one player doing piss poor in a game.
I guess what I'd really prefer is AR to be added. So bored of the same 15 heroes in every single game.
I know the feeling, some of my friends sometimes refuse to play with me because they don't want to get stomped on. Then again there really isn't a good solution to skill disparity to people you play with because if you get a smurf account it's really unfair to the people you play against.
I don't know about picking same 15 heroes though. I had a losing streak of 5 or 6 games and reverted to picking Clockwerk every game and won 8 games in a row or something, 2 or 3 them being frontpage games. The tryhard sentiment is pretty old though, I enjoy playing support and usually take it as a compliment.
I used to play RD in DotA but without all the heroes in the game it feels pointless.
Kind of answered your post too but I'll just add that I mostly see the same heroes in solo queue. Invoker especially is in every-single-game. Other extremely frequent picks are what you'd expect. Wolf, Furion, Morph, etc.
And yeah, it sucks when SD screws you or your team on picks. Multiple times I've had three supports or three carries, and it's really frustrating if your team is already heavy on carries, or heavy on not-carries (I won't call them supports because few pubs are willing to actually play as a support.) That, or the enemy team will get much stronger heroes than your team got... it's really frustrating when the enemy team gets something like Naga (and that goddamn bullshit ulti) or a Lycan that knows what necrobook is and your team went full retard and picked Spiritbreaker and Bloodseeker.
SB would be a fantastic hero if BKB/Repel didn't completely counter him. His ulti needs to stun through BKB or something, I think he'd actually be a viable hero if that happened.
I will admit, the cooldown on Slithice ult at level 3 is just hilarious. The infamous sleep/TP scroll allows her to infinitely split push and you really just can't do anything about it when her ult has the same cooldown as the TP scroll.
I also agree that SB ult needs to stun BKBs even if it doesn't do damage anymore. I was surprised when you said it didn't, I could've sworn it did. I tested it and laughed pretty hard when I saw it did literally nothing but teleport him to the target. Still, as early as level 7 he can max his charge and become one scary ganker. Between charge and ult alone he can stun someone for near 5 seconds and provides allies with the movespeed to make following up on the chase, if they even survive that, easy. He also comes pre-equipped with enough tankability to survive a little bit of focus or tower diving as early as level 7. The second he hits 6 he should be getting kills across the map, hands down. Most heroes can't do a lot about it if his teammates are paying attention to the ganks.
Basically, what I'm hearing is that this current meta needs more gank carries =p
Farming heroes to get big used to be such a common trend. Luna, BS, SB, SA, Fletch, Weaver, Razor.
SB would be a great pick if he fit into the meta better, and wasn't hard countered by magic immunity. MoM is really common on him, but in my opinion it's a lot better to get a quick BKB after the essentials so they can't stop you from charging them, and then follow that up with a Mjollnir for some magic damage, some AOE for pushing/counterpushing, and the attack speed. Maelstrom's really cheap so it could be a midway item to get between your essentials and finishing BKB.
A word of warning to all who consider trying out DOTA 2 when it comes out, this game has nothing to do with LoL as far as gameplay goes.
In HoN any hero, even a mage like Veigar or a healer like Soraka, can get fed and "out dps" carries - not just that, but in LoL every hero can scale very well and benefits greatly from items.
In Dota (and dota 2) support type of heroes are expected (and even demanded) to spend even over 80% of their gold income (which is VERY low) on wards, potions, teleport scrolls, other consumables - not just for themselves, but for all the carries/gankers that need to save up their own money.
You, as a support/initiator/pusher and even a ganker, are expected to give gold, limb and life to protect and serve your carry - who in turn will carry you to victory, assuming he knows what he is doing.
It is a specific and potentially infuriating experience, since (as a non-carry) you are literally less important - even a lesser life form - than your carry.
Hence the saying goes, LoL is for casuals (where everyone wants a "kinda equal" role/chance/importance in the team) while Dota is for a tad more dedicated crowd that do not mind doing 45 minutes of "slaving" to your carry in order to win.
Timewalking - ALL dungeons/raids in WoW available at any time (LFD matchmaking style)!
Maybe if you're trying really hard to be a babysitter but in my experience when it comes to pub play, supports are far, far, far more, shall I say "independent" in DotA than in LoL. A wardbitch Sona will contribute a lot less to a fight, both when it comes to damage and when it comes to actual 'support' than say a Witch Doctor or Rhasta.
The only exception to supports being "independent" really is when you get to really lategame where you've basically got carries killing people left and right without even trying but even in LoL, a Sona by 50 minutes wouldn't expect a lot more than 2 aura items and maybe a Rabadon's or Rylai's at best.
TLDR: Supports in LoL are weakasfuck.
