I've played Guild Wars 2 with a controller for years now. Tried out as many programs and controller setups I could get my hands on and I finally think I have something I can share with others who may be interested in trying this out or looking for some new tips and tricks on making this work. With Action Cam, I honestly don't know why the dev's havent made controller support a thing yet. This MMO is one of the best for controller due to the small amount of abilities used.
The programs I use are Xpadder and the Steam Overlay controller support with an Xbox One controller. I've also set up a layout using an actual Steam controller as well.
From all the discussions I've read about controller support, I've seen some good ones, but they all seem to be lacking in one or two things still. If anyone shows interest in learning my setup or giving it a shot, I'll post more detailed information about what sets I use in Xpadder, along with button layout's and extra functions, etc...
