Legion Remix is like the worst kept secret at this point. blizzard haven't announced it publicly but there were comments about going back to Legion sooner than expected and also that Remix is likely to be this year.;
Combine this with 11.3 being increasingly unlikely and it all adds up to Remix launching in 11.2, maybe 11.2.5, but I expect 11.2. So that's roughly August this year.
And yes, WoW is really a Remix waiting room for me at this point. MoP Remix was incredibly fun (other than the 60-70 suckage and after Bronze drops were buffed), easily the best LTM Blizzard has ever had.
I hope they don't screw it up. My expectation is that the Legion artifact weapon will be the new MoP Remix cloak. I did like that MoP Remix had som erelatively short raids (ie ToES, even MSV). Long raids (particularly SoO) kinda sucked until it became a cakewalk. Trial of Valor was the only shorter raid. Every other Legion raid fits the modern formula of ~8 bosses.
It'll be interesting to see what they do with order halls. Also, Legion added the M+ dungeon tier whereas MoP (and thus Remix) only had Normal and Heroic.
Bring on Legion Remix.
