Controller support is 100% possible. I do it with an xpadder program and a PS4 controller. A lot of you might think it's super complicated but it's not. It obviously not perfect but it definitely gives you that console feel. My controller set up is really nice for farming and questing but I wouldn't recommend it for pvp.
Some of you have asked how do you use skills? Basically I have the triggers and bumpers mapped out so when you hold one of them in certain buttons on the controller will become skills until I let go of that trigger button. Each trigger being held in maps out different buffs or skills. This basically gives you an infinite number of buttons.
i would love to borrow your keypad setup for this
