This thread is meant for the devs, who at least claim to watch this forum, and anyone else who needs to be warned.
Vanilla player here. Played all expansions and none of them ever seemed so bad as this one. These are the main issues.
1. Extreme lack of content. Nothing to do outside raid hours and/or arena/bg hours (if that's your thing). There are no reps to be farmed. There are no dailies to do. Even farming hcs gives absolutely nothing and you don't even need to grind them for gear, as gear is now in the AH as crafted and boe epics, some of which are really cheap, like as low as 500g for the engineering items, not to mention you can queue Ashran and get a full set of blues in like 2 or 3 hours, and ofc LFR.
2. Professions? Destroyed. Professions no longer have perks that are only available to the person who has the actual profession. For example, Engineering. The only ever reason to pick it up was because of the toys and gadgets that were only available to the engineer. Nope. In WoD those are common items and can be traded, also they are worth nothing so you can't even make gold with them.
3. PVP balance. Now I'm not the best of pvp players but apparently if you don't play a dk, feral druid or hunter, you're pretty much screwed as these classes are insanely OP and there are tons of people playing them, especially hunters, which means you are going to be abused over and over by one or more of these. I just want Ghostcrawler back at this point as Holinka is fucking useless.
You got classes that are, literally, useless in pvp. Talking about dps shamans and dps monks. And what's more astonishing is that Holinka has no idea this issue exists, and doesn't tweak these guys at all. Oh wait, he tweaked some pvelol numbers.
Almost all of the big pvp names have quit wow by now, last to bail was Thyraz. You only have people who make a living out of streaming wow like Swifty and Bajheera, right now, who can't leave as it's their job.
4. Ashran. A total joke, which is no surprise considering it's Holinka's "baby" - the person responsible for the shittiest pvp balance since vanilla. From having huge queues and people avoiding pvp, it now has 2 min queues and one or the other faction deathballing events and overruning the opponents wherever they try to completely events as well. It's so retarded that if your faction doesn't faceroll events, you can just exit this...joke of a pvp environment and requeue in the hopes of entering another instance of it where your faction may be the one owning the events. Blizzard should just cut their losses and close down this shit.
I'm sure this thread will now be swarmed with white knights who are as clueless as Holinka, and MoP babies for whom the game is still new and they still have pet battles and achievements to accomplish (content, bros), but eventually everyone will reach the same conclusion we vets have reached. So to all these guys I can only say one thing: Enjoy your World of Garrisoncraft while you still feel like this is content.
Now troll away.
