Hi, I have the n52, hoping one day it might break.. so I have a reason to buy a nice black and blue shiny one...

I find it perfect, I use the thumb key as a shift, the red button as ctrl and then thirteen keys to play with.

I use the numpad for back, strafe left, strafe right and target mob (instead of forwards, as I can use the mouse to walk forwards)

Because it's five keys wide, I can easily co-ordinate my heals across the five characters - the middle row is for this.. with ctrl and shift to choose alternative spells. The top row I use for aggro reduction / taunt, follow, dps, dots and pala threat building.

Bottom row I use for drink, accept all, prayer of healing and err.. i don't remember.. hmm have I even assigned the last one??

Anyway, I only ever need go back to the keyboard when I need to type something.. everything else I think I can do from the pad
