Honestly I'd like so see a return of the tabard system. Maybe they implement it kinda like they did in MoP where let's say you need to get exalted with the rep on one character before you unlock a BoA tabard. Also LFR killed the incentive to raid for allot of people, it's actually hurting the game allot more then it's helping it no matter how many people use LFR, but Blizzard will ignore this since they see a ton of people using the system they think it's doing well. Now we'll have LFR, Hardmode LFR, normals and heroics all with the same gear. Sure the ilvl is different but that's quite meaningless. I just think having an exclusive game is much better then having a completely inclusive afk / drool on keyboard and still get loot game. But even with its major flaws, and its series of loot piñatas, I'll still keep playing because I've found a good group of people to raid casually with. I think for allot of people the biggest reason they keep playing is the people they play with.
