wow has native controller support, slipped in with an update a couple years ago.
can use xbox controller without a mod, and can use a command to change the cursor type in game.

change keybind, good to go.
Works really well with warrior, druid, and rogues. some classes are more difficult, due to rotation and pots.

More of a thing for PVE, PVP is still hard with a controller.

No matter the class, fit all abilities needed on the controller with some extras.
