It works great, but needs a bit of tweaking. Targeting distant foes and picking up specific loot from a pile of items can be tricky sometimes, but nothing remotely game breaking.
I personally changed the touch pad tu function as a mouse for inventory management.
For comparison, I have a few hundred hours in Diablo 3 (PS4 version) which have a great controller scheme and for me it’s the best controller experience of an arpg on the market so far. GD its not far behind, but you might need to personalize it.
