Saving Limit Breaks as a coup de grâce is stupid.

Ive already seen a blm get yelled at for doing that. If only because appatently only melee dps should lb, regardless of the situation. ;p

That is awful. That kind of hierarchical nonsense wherein someone calls 'dibs' on a group resource is worthy of ten thousand kicks to the metaphorical shin. Sometimes the tank pulls a dumb move and needs to be saved. Sometimes the group is in desperate need of a heal. Sometimes a hive of bugs needs the bottom of the boot! If the group wipes, then no-one gets to use the damn bar.

I found the opposite true: noone uses the LB. The LB could fill all the way during a boss and noone uses it. As a tank, I have to actually tell someone to before it will go off. People are way too timid when it comes to using the LB.

From my perspective, I'll use LB when I have a safe opening. It's not fun getting animation locked then getting trampled to death + blown up in flame pillars + having my SICKNESS PURGED.

Which might be caused by the other mentioned mentality. They have seen too many times someone else being yelled at for using it "wrong", "wrong" time or "wrong" class or what have you. I try to use the LB on boss fights as soon as it's filled, it does the same amount of damage anyway. Only delay it if I know the boss is prone to invulnerability bouts so it won't hit those.

I follow Monk mentality: if the LB (or LB difference between melee and other) is only doing some 12k damage just let me keep my 8 seconds and have the 500 dps ranged do it instead...
Wait until 5%, ranged still hasn't used it. Well, it'd just be overkill by now. Might as well not get hit by AoEs...

It's not a trump card if you don't use it. Are you people having some kind of anime-esque power fantasy where you're pointing your fingers at the monster and screaming: "OBLITERATE! AHHHHHH!"

Haven't you seen the lengthy macros invoking the 12 to fill them with power so they may smite their enemies, or something along those lines? It seems to be a fairly common thing.

Sorry... but I LB trash mobs at the drop of a hat. Much rather push the run there then shave off .0000001 sec off the final boss fight because the DRG finally wants to pull the trigger as the screen begins to turn black on a boss that has done nothing to scare the party in the slightest.

The other day I was in a group of all green leaves during leveling roulette who were close to kicking me for it. Seriously lectured hard after that one. I just didn't have it in me to fight back... haha.

When PuGing
LB1 on first boss is almost always out of the question because the LB gauge almost never fills before the boss is dead.
As melee, I will LB the 2nd boss to start the fight, this allows enough time for the LB gauge to fill again before the 3rd boss fight starts.
As ranged/caster, I will LB a large trash pull or two.

When with my FC mates
As Healer and Tank, we make a game of it to see which, most inappropriate LB can be used first.

Imo using LB early is the better option in most cases, several jobs have "finishing" moves only usable in the last 20%:
NIN: Assassinate
MCH: Heartbreak
BRD:Misery's End
WAR: Mercy stroke (also available as x-class)
So using LB to take the boss TO the last 20% will shorthen the fight more than using LB to skip the last part of the fight.
Exception being fights where you can skip a mechanic in the last part of the fight (only dungeon that i can think of right now being Brayflox HM where you can skip the last set of adds and the big bomb)
