Given we've only had the first expansion so far this year, which is usually the weakest, it is pretty clear the devs want to power creep the ever living shit out of the game. For rotationless wild, if things weren't already bad, they aren't going to get any better.
There will be more Stealer of Souls, and even if there weren't what is all ready there is a foundation of complete BS.
Arena, Battlegrounds and Standard are all good modes. The game still lives.
