As much as I used to love WoW and this Trailer is awesome, I just don't think I can justify the game anymore. The content drought of MoP and the embarrassment that was WoD decimated both of my guilds and my friends list and the community of the game itself is now...well, "complete ass" is a diplomatic way of saying it I suppose.
There is the gameplay where nearly every single class has been incredibly dumbed down even from MoP and almost every spec is completely uninteresting to play.
Then there is Legion's reward/progression system which involves the Alt and Off-Spec destroying Artifact Power grind AND the "Yo dog, we heard you like RNG so we put some RNG in your RNG's RNG so you can RNG while your RNG RNGs" with Warforging, Titanforging and how Legendaries are handed out.
And worst is probably the Legendaries themselves, which their RNG system of handing out sucks because several classes and specs are completely crippled or significantly less viable unless they get a certain Legendary coughHolyPriestcough.
But goddamn, can Blizzard make a trailer to prey on a guy's temptation to come back.
