I just tried out the controller feature on my PC today, and I actually love it quite a bit. Having access to multiple spells without having to switch between them feels much better than the classic controls.
One quick suggestion/issue I have with the controller features is that when trying to farm something like Nihlathak in hell mode as a cold sorc, it’s hard to have the controller target him so that I can find out if he’s cold immune or not. I think something auto-showing boss enemy health bars/resistances would be beneficial in these situations, especially since he’s surrounded by so many of his minions. Whenever I do D Key runs, I usually will just leave if I see he’s cold immune, and that’s much easier with a mouse just being able to mouse over him.
