It's good lol. It's just d2 but doesn't hurt my eyes but has the same vibe it used to back in the day.
Also the controller support works surprisingly well, and rumble feed back from spells actually adds some depth I didn't expect. Works sort of how FFXIV does it, but slightly less complicated. Intuitive even.
Nah, there's a full skillbar for controllers but mouse still has to be manually bound via the two slots for some reason
No idea about the rest, not my wheelhouse
