I tried using the ranged LB2 in Castrum Meridianum to wipe out the last mob before Livia (the last boss of that dun).
But was too slow to it and the Tank ran past me on his way back to the cannons... so I only got 1 mob down, my original target.
I got called out "that was totally pointless"

I gotta agree, that was pointless, but the LB bar resets as soon as you start the fight with Livia and all those mobs die instantly from the LB so an LB wipe is actually faster than dragging back to the cannons :|

Still... the shame .___.
