Combining some buttons into one

I manage too, but it's far busier to play than, say, Dark Knight, which also has much simpler mitigation. You will be switching to different crossbars more often than most other classes, guaranteed, for identical DPS. And for what? A class doesn't need to be carpal tunnel-y to be engaging.

I play both GNB and DRK, and I wouldn't really say I switch (use expanded) hotbars more on one than the other.
In both cases I have pretty much all the offensive skills in one set of hotbars, plus Heart of Stone/TBN, then the expanded bars are cooldowns, passive abilities (like blood weapon) limit break, etc.
