I must be missing something because today (June 3, 2021) the battle.net app and the wow installer app both require rosetta and do not run natively in arm.
Hopefully Blizzard ports more of its ~10 Mac games to M1 Mac. And it's probably asking too much, but if the games can run on M1, can they be ported to run on A14 (iPad) which also supports mice/keyboards? It's almost the same CPU as M1. I would point out that iOS now supports mice (one of which is required for most Blizzard desktop games.)
