F2P is just an eventuallity, tokens were the first concession.
I can't see vanilla ever happening and it would be shit, people have huge nostalgia glasses in this area.
Skill trees aren't coming back. The current talent system is superior in that it actually gives you choice and gameplay shifts.
Didn't Wildstar teach people anything? They don't really want what they claim to want. There isn't really a market for the things they claim would be huge hits. Wildstar was a better game than vanilla WoW and it was/is a fucking disaster.
Basically, please Blizzard give us vanilla servers so people will finally STFU about them. They will play them and get bored, nostalgia will wear off, and the rest of us will finally stop having to hear about how much better vanilla WoW was than anything since.
Oh and when they finally give you vanilla servers have fun storing your mounts, quest items, reagents, and tons of other stuff in your 12 slot bags, and walking everywhere until level 40 and being slow as shit until cap. Also have fun endlessly farming raid mats and keeping a 40 man raid team. Don't forget your 60 minute hearth and your only decent spec per class and no dual spec. Have fun visiting 4 zones to complete a single quest, or having a fraction of the flight points per zone. Bleh, I'll just leave this here, I could sit here all day talking about things that were much worse in vanilla than even today's WoW:

As for what I want to see in WoW. No fucking garrisons or shipyards. Finally allow cross faction play, factions in this "War" have meant virtually nothing anyway. I want a new class and a new race wouldn't hurt. And probably the least possible, I'd like a way to level my character outside of levels. Some sort of AA or hero level type stuff would make being a max level more than just about the raids.
