Saving all that LB for the final boss is a waste, unless you get fancy by doing a ranged DPS LB pull on the boss, or the second tank LB right before the MT tank pulls (there is an animation lock, so if the MT LBs and then pulls, it's largely wasted) to give him a shield. Because, after all, the LB bars will empty upon boss agro.
