I LOVE THE NAGA RAZOR:
MM hunter, bound main rotation 1-6, multi shot 7, 8 - disengage, "shift 8" deflection, 9 readiness, 10-12 (rear row) used for CDs, to stack them its really easy, you just run your thumb up the back row.... (you can also sub you keyboard hand onto the reg number row if you need to for a moment to stretch your right hand mid fight, while still maintaining your rotation)...... silence shot forward mouse button, scatter "shift forward mouse btn" and conc "ctrl forward mouse button" random things on rear mouse button, and mouse wheel. , use Q, E, R, X, and C on keyboard extensively for all sorts of things, ie: "Shift C" - trap launcher, just keep holding Shift, because "Shift, 1 - 5" are different traps. V darkflight, Shift V rocketboots(belt).
