Well... You can use the gamepad-style "Pause" menu, which I quite like. Ground targeting is going to be awkward no matter what, but it's not too bad with a controller once you get used to it, and I assume keyboard is similar (if I can aim Sacred Soil on ADS while dodging lasers using a controller, I'm sure someone can with only a keyboard as well). Were there even ground-targeted abilities in XI or 1.0? Seriously, I don't remember. And as far as I'm aware, the camera control buttons can be remapped, and the only complaint I have about them is the lack of on-the-fly centering adjustment (sometimes I would like the camera to NOT be centered directly on my character at a fixed height), which is a problem with the game design and not the input method, since you can't do this with a mouse either.
