it's a tablet so I'd use the touch screen

So does the Xbox controller but I'm able to use tons of abilities via button combos. After a while it becomes muscle memory, like playing a fighting game. For all the naysayers, I am achieving top dps in LFR and tanking heavy-movement fights (like Shannox) with this method.

Core abilities (11)
A, B, X, Y, Back, Start, LB
U, D, L, R

Secondary abilities (11)
RB + A, RB + B, RB + X, RB + Y, RB + Back, RB + Start
RB + U, RB + D, RB + L, RB + R

WASD: Left analog
Jump: Left stick click

Mouse turning: Right analog
Tab target: Right stick click

Since these Fiona controllers don't appear to have as many FACE buttons you could just add one more button combo, for example: A, RB + A, LB + A.... that would be 3 x 8 face buttons = 24 abilities mapped.

IAW(XBL), that seems like an awful lot of work for something that is very simply done with a keyboard.

Not to mention that in wow people type stuff in in-game chat all the time too, so unless you're going to forgo that aspect of it... and then I have to wonder how you would do things like put items on the AH.

It's not like I don't have a keyboard right there in front of me, constantly using it as well for all the usual things. Let me put it to you this way... would you rather play Mario 64 with a controller or with a keyboard and mouse? THAT is what it's like playing my character. I am able to move him around with perfect precision. No it's not complicated at all. The concept is difficult to grasp but in practice it actually makes the game easier to play. Go look up Xpadder on youtube.
