Who is supposed to use limit break and when?

Not to mention with incorrect information as well... The reason they state they wont use it is because their Egi is somehow a better damage dealer then they are, so any other DD should use it. They neglected to note the fact that It is based off the entire party's damage not theirs alone that effect it.

And someone feel free to correct me if im wrong, but i thought the person who res'd the thread had the heirarchy wrong too. My understanding is that the per-target damage goes MELEE>Ranged>caster. But with that said, if the situation calls for a caster limit break doesnt the group lose more overall damage if the BLM activates it? If i stop what im doing for the 10ish(ive never actually timed it, but the higher level LBs feel like they take forever) seconds to trigger, cast, and animation-lock a limit im resigning myself to only doing thunder damage(40 potency per tick) rather then 3ish active casts(and for reference, a single fire 4 cast under normal conditions is roughly 529.2 potency). A summoner who does the same is also giving up active casting, but potentially has multiple dots going plus a pet doing damage for them while they are locked into flaring the world - thus an overall gain for the group since the damage from the limit itself should be the same.

Unless im remembering it all wrong because im tired.

Depends on situation also, if you have a large clump of enemies that need to go down and the group does not think it could dps in time, caster lb would be the way to go. Single target enemies like bosses or a target that needs to go down because of death otherwise, Melee would be best.
Other limit breaks such as Bard does have it's use at times, obviously this was an old post as Bard lb is no longer a heal one, lol

Using Melee Limit Break as the standard to compare to: Caster Limit Break is roughly 2/3 of Melee Limit Break and Ranged Limit Break is roughly 90% of Caster Limit Break. That's right. Ranged Limit Break is almost as useless as it was pre-3.0! Weaker than Caster Limit Break, very thin so it's easy to miss enemies with (like every line attack), and just to make sure it's awful, the person using it can't even see its area of effect. I don't know why the devs decided to be total idiots here. However, because it is still 90% of Caster Limit Break's damage, it's still considerably better than Melee Limit Break against even 2 enemies. Melee Limit Break is only to be used for single-target fights or if Caster/Ranged Limit Break would cause too much overkill.

I've never bothered with the math to figure out if BLM using Level 1 Limit Break, Skyshard, on a single target is actually a DPS loss or not, but I'm pretty sure it is unless it kills the enemy, obviously. Of course SMN using Level 1 Limit Break on a single target is a DPS gain as long as they cast it right after Fester so that its cooldown is going during Skyshard.
