Final Fantasy XIV Online works well on controller, and I wouldn’t call it simpler than WoW.
It uses the two triggers as modifiers for the face buttons and d-pad, letting you quickly hit any of 16 different hotbar actions by holding a trigger and hitting a button. Then one of the bumpers is also a modifier, to swap between 8 different hotbar sets. There’s similar setup for target selection.
I play it on PC and find it more comfortable/casual using the controller. Not to say it’s a superior mechanism, I just don’t think the game is any simpler due to being on PS4 as well. And the PS4 version also supports m/k! :)
