Should each role have a separate limit gauge?

[Destous]

The only separate LB bars I've seen are in pvp and to be fair it would get fairly broken with all the types of lb3's since if timed well you could just cheese through anything so balance would be a major issue

The only cheesing I can see happening is with healer LBs, but tank LBs are pretty insignificant, and DPS LB3 has become mandatory in every HW raid. Outside of separate gauges for LB, I can't see anything other than DPS LB3 being used.
