Control mappings have face buttons and R1/R2 as attacks, L1/L2 as button layer modifiers, Joystick mouse and more. F-keys are on the d-pad, and most mouse related functions are active while holding L1. Pressing L2+R2 heals. Back button is your "interact. L1 + R3 switches between "action" camera and regular mouse mode for aiming. Action camera is better for combat, and is the mode I use like 90% of the time. Dodge is on R3. L3 swaps weapons. There's also key combos for all the mounts, special action abilities (N key, on L2+back)... basically, everything you could possibly want to do in-game, there's a controller way to do it. You may need to remap some of the mount buttons, I forget if I did custom mappings for some of those, as I have a lot of mounts (everything except roller beetle and gryffon).

Hope it works for you. I think it's a great config, but my perspective may be skewed since I'm highly accustomed to it from muscle memory and using it for years (with Xpadder even, before steam controller mapping was a thing). I've used this config for every single class in the game and dialed it in so I can play literally any class without issues, including ones that have a number of aiming skills like engineer and elementalist. Actually, elementalist is a blast for this, dpad was perfect for switching elements compared to fumbling with F-keys.
