That said, if the team's AoE damage is less than 75% per target than its single-target damage, which it almost always is, it is at least better to finish an AoE pull with LB than to finish off a boss. Moreover, some healer GCDs of damage might be saved by using the LB early enough to overkill as few mobs as possible, more quickly removing whichever mobs were least lucky against crits and reducing tank damage taken.
In dungeon final boss fights as RDM I will always let the other dps use the LB unless I know I'm doing less than or roughly equal to the dps they are doing. Most fights will be over by the time the nation lock ends anyway by the point I give up waiting on a melee to use it, and the caster one is pretty pitiful vs single target. If the other dps is clearly doing far less damage than me then it really pains me to use the LB l, especially if they're melee, and will often not use it. The weaker dps, if there's a significant disparity, should use it otherwise most of the impact of it is lost since your main damage output is animation locked for multiple GCD.

I will use it on the last trash pull of a dungeon if it is a full pull, my Moulinet spam isn't going to be available for the fight... and I actually remember. I've never had anyone yell at me for it, although I have had a couple people chat "..." after I've done it which I just ignored.
