Limit Break for Tank, is it useful? when and where can I use it? Should SE change it?

[Wobi]

So far, I have not been able to figure out a useful usage for the Tank LB. I even tried to use LB3 against titan AOE after we missd the heart and it had no effect and we all died anyway.

I was wondering if anyone has used Tank LB and find it useful somewhere?

Should we ask for a change?

If you get to the point where it could be useful the battle is already over, if you need something like that to survive then clearing the content is not gonna happen with that group. They could add all sorts of buffs to it but people will always opt for a damage LB in any competent group. Maybe a healer LB3 as a last ditch effort. Now it could be possible for SE to add a gimick of some sort of damage attack that will hit the party and no way you can heal through the damage to give a reason to pop the Tank LB so everyone survives. Something like a Giant meteor crashing down on the party or something similarly crazy, but that's the only reason I can think to use it.
