Though we all know how strong the believe in their god, no, Mac is, its beloved users tend to disregard some minor facts. Yes, the new CPU is kinda nice, a good SoC for a tablet or an entry level notebook. But playing a 3D-game takes some more power that the Apple GPU don't really have. Yes, it's faster than an Intel based built-in iCore-GPU. But that is not really worth mentioning. The M1 8-Core GPU is not exchangeable, it's fixed and is as fast as a low end new mobile discrete GPU by AMD or NVidia. Running this Apple-GPU with non optimized and deprecated OpenGL-code on a completely new platform - well, you really need to love your Mac to willingly do so. But, looking from the other side, a publisher needs to be sure to give customers a good product - which is quite hard on a Mac without building a new client from scratch. Comparing the comic-style WoW with GW2 is not really useful either, WoW is available on the iPhone for quite some time.
So, well, be happy with your fresh and new M1-SoC, but do not expect many game publishers jumping on the Metal & Mx-train. Emulations and Bootcamp is also impossible, stopping the Mac-client is a kinda sad but logical thing to do. Players with an Intel-Mac can still make a Windows- or Linux-partition (Linux Mint & Lutris is fine if the hardware is supported).
