Maybe instead of having a block, replace 2 or 3 with an altered skill. For example in one of the videos that was linked before, the bo user spins the staff in front of him in a flurry. Replacing the number 2 which is a pretty pathetic gap closer with a casting flurry that does damage, applies vulnerability with each hit, and stops (not reflect) projectiles, similar to the berserker spec sword flurry. That would be more fitting than a straight up block to me for staff. That way it would be an offensive ability against melee oriented classes but more of a defensive ability against someone trying to use projectiles from range. And by flurry I don’t mean similar to the way it spins in the 3rd attack animation. I mean more like how in the video he goes back and forth to each side, the pinky leads and the two handed flurry he did.
