Legion Remix testing has been extended on the 11.2.5 PTR. The character select screen countdown now says 6 days are remaining before the game mode ends, which means testing will conclude on September 15, as opposed to this week, as initially intended.

Why Did the Testing Get Extended?
While Blizzard has recently implemented certain improvements for Legion Remix, the game mode feels more like Classic Legion as opposed to MoP Remix, where you could outgear content very fast and virtually spam your way through everything. Remember Warriors constantly pressing Heroic Leap and Whirlwind while one-shotting everything? Well, this intense power creep isn’t possible in the current iteration of Legion Remix on the PTR. Hopefully, with extended testing, Blizzard will bring the event closer to its MoP counterpart and remove phases altogether.
