I was in a Royal Menagerie group where I had to use LB3 2 times so we could kill the boss (yes, it was that bad).

This is after a SAM threw a fit because we asked them not to use LB3 at all, after we'd already wiped twice.

So, what I've learned is that in a PUG, the Limit Break is mine and you'll have to deal with it until we, the other healer and I, deem you competent enough to let you use it. Then it's melee DPS > Caster > Ranged. Or whoever wants to see their animation. I don't care.

I know this sounds arrogant but I'm just trying to get my party to finish the duty successfully and there are times when I've got to use every tool at my disposal, including the Limit Break. That's just me doing my job.
