Patient Gamers
A gaming community free from the hype and oversaturation of current releases, catering to gamers who wait at least 12 months after release to play a game. Whether it's price, waiting for bugs/issues to be patched, DLC to be released, don't meet the system requirements, or just haven't had the time to keep up with the latest releases.

For just a solid combat system, hogwarts. Was really surprised. They had some solid people design and build it. Really stood out against the rest of the game which wasn't bad by any stretch just repetitive. There are some serious combat challenges too. Just make sure you play on hard. It really needed one difficulty higher tbh.
Theoretically, Immortals of Aveum could be good for this. It’s basically a shooter, but with spellcasting for the shots.
Lots of good suggestions already, adding Magicmaker as a fun build-your-own-spells game: https://store.steampowered.com/app/319250/Magicmaker/

Tbh, WoW is fun to wield magic in. There are many different styles and planning a rotation that is effective and effecient is fun.
