I had Legends of the Sword Coast on X-Box One, and the control scheme was too hard to memorize. Depending on whether the + key was up/down/left/right all the triggers and buttons had different functions, not being very used to controllers I gave up on trying to play it. If the controller implemented it as maybe the + key brings up different quick item/actions that would maybe be do-able. I think I'll try out DOS2 with a controller and see how that works, but keyboard and mouse are fine for turned based.
Same here I mainly use controls for fighting games like Dragon Ball Xenoverse but when it comes down to rpg games I just stick to a mouse and keyboard
