I would ROT AWAY if BH got buffed like that, it needs tossed out first and foremost. Like someone had suggested who apparently is a long time PvP'er just make it where LB doesn't charge passively but requires being in combat to get(At least in Frontlines, they never mentioned CC AFAIK). Forcing classes to engage in combat to get their LB would mean you could actually have more active and meaningful fighting and the numbers can make sense, could even have it where your LB gets charged by 10% or some shit for every kill you get with a non-LB skill so there isn't LB chaining but ways to reward people for actively taking risks and getting into combat.
