Is limit break not a thing?

[Dualgunner]

If they arent paying attention to and anticipating limit break, odds are they also arent coming anywhere close to maximizing their dps potential anyways.

There are two ways to go with this logic: the "realize how dumb the average person is, and then realize half of them are dumber than that" angle where we can agree that yes, odds are they aren't, but then again odds are they aren't anyway. The other is the one where I disagree with you, and say that actually, people who avoid the LB3 entirely are probably a lot closer to optimizing their job than not. There isn't a job in the game that can fit a 7-10 second delay in actions and still be called "optimal".

Regarding the topic itself, I'd say limit break serves a very fun purpose that sadly loses effect the more effective the team is: it's a big nuke to drop on the enemy. It makes you feel powerful, like you're really using the ultimate power available to you through your job crystal and your connection to your team. In more casual content, it feels AMAZING to let loose a Dragonsong Dive, or a Chimatsuri. Personally speaking I love the animation for Doom of the Living, and always find it hilarious to blind everyone with Vermilion Scourge or summon a satellite laserbeam.

Something I did notice is, going through the team managing to get through the fight without dps Limit Breaking at all is a sign of prestige on us: we were strong enough to not need it, and with our coordination, we were probably stronger without it. Is it a good design to make a system where teamwork coordination and skill completely outdoes and forces obsolescence on a job's ultimate skill? I suppose that's up to each individual to decide.

Personally speaking, I think it fills the niches it needs to fill for most parties: an awesomely animated asskicking attack; a crutch to stand on to make up for lost DPS; a tremendous AOE nuke; a quick "Oh shit" button; and finally, something to avoid like the plague because we don't need no Limit Break in these parts.
