Mechanically 25 man is way harder, the raid damage is higher so you need to spread out and organize the raid cooldowns you have aviable, thus putting more strain on healers/DPS/raidleaders to get it right, there's more targets to CC/Interrupt making it much harder to organize, and one person dead means a wipe on heroic just like it does in 10 man. And because of less space, more people have to be concerned with AOE-damaging abilities which are present on almost every encounter this tier.
See how ignorant you sound? I just did the exact same as you did, just with 25 man, and all of the points are equally valid to yours. Blizzard are, contrary to belief, not dumb. If there's more Raid CD's aviable to 25 mans, that's because things do more *damage* in 25 mans. As an example, Durumu's Light Spectrum beams does 125K shared damage per tick to people in 10 man, and 375K shared dmg per tick to 25 man - thats not a x2.5 increase, but a x3, because 25 mans have more raid cds aviable, thus they have to up the damage.
The "combat ress" argument that people keep using also doesn't mean anything on "bleeding edge" progress - one dead person, be it 4% or 10% of a raids' overall power, will result in a wipe on any well-tuned boss fight (Garalon, Garajal, Sha of Fear, Protectors, Tsulong and the list goes on). You don't get to the point where you can lose raid members and still defeat the boss untill it's either on farm, nerfed, or you simply overgear it brutally.
They have done their best to make the two raid sizes equal in difficulty, and honestly, it isn't going to get much better. It seems to me like 10 mans might be a bit easier this time around in normals (remember, we haven't even SEEN heroics yet), because of the fact that so many of the encounters are reliant on teamwork - having just one person (or two) do something, as opposed to five, makes your chance of success MUCH higher in a 10 man enviroment on fights like Ji Kun, Dark Animus, Iron Qon and Lei Shen. On the other hand, having more people on a fight like Horridon and Primordius works to 25 man's advantage.
Can we just agree that the two sizes are different, shouldn't be compared, and that the number of 25 man guilds have been steadily plummeting because people like myself (the raid / guild leaders) can't be bothered herding 25 cats when we can herd 10 instead? Thanks ;_;.
As for the "ontopic" Thunder Forge deal -
I don't see an issue. 25 Man is harder to organize (and before you claim otherwise, kindly provide evidence that you've been the raidleader of both a 10 and 25 man heroic raid team. I can't be bothered to discuss with people that "thinks" they know what it's like), and getting recognised for that is quite nice. Would I have been happy with vanity pets/mounts instead of higher item levels? Sure. But I'm not going to complain about this, either.
