Is limit break not a thing?

I was under the impression that in raids, you generally want to save LB3 to use during add phases unless using it ASAP will allow you to get a second melee LB3 off over the course of a fight.

Though as far as SB goes, outside of it being virtually required for the OS3 add phase, it's only applicable for the OS7 Bibliotaph or during the Shinryu Extreme burn phase to nuke both of his wings.

As far as dungeons go, it's most time efficient to use a caster LB to blow up a big pull of 5+ enemies. Otherwise, saving it for a melee LB2 on the final boss is probably ideal.

Tank LB3 was needed for Byakko EX if you wanted to just breeze through the run almost flawlessly during that second add phase. I have seen and been in parties where they've forgone it in order to just nuke the add themselves, but the DPS were spot on with no hiccups. You won't always find that in party finder.

However, I've also seen tank LB2 used where people STILL survived with maybe a minimal death or two on the second add phase as well. But, healers have to be on duty and fairly good as well for the damage mitigation and capping everyone off the moment you're not stunned anymore and avoid Fire & Lightning.
