I changed my entire bottom bar to <W,A,D,S,F,Q,E,C,R,Z,X> My middle mouse is force leap. Alt-d is next target. Tab is target center. Shift-w is a skill. Numbers 1-3 are my 3 minute cooldowns. If I want to look behind me, I press num lock. This binding works well for me. I did it for solo'ing, not Pvp. It's just easier to use.
