Limit Break for Tank, is it useful? when and where can I use it? Should SE change it?

In my limited experience, the only usefulness is to trivialize content by allowing you to circumvent intended mechanics.

For example, the tank LB means you can ignore the pillars in Garuda, story mode. It's obvious the designers wanted players to watch their positioning and not splash the pillars with AoE, and it's fairly obvious that they wanted us to AoE the adds down before they did significant damage to the pillars, but you can pretty much stand anywhere and casually kill the adds, using the tank LB for her ultimate.

Who the hell knows when you ALWAYS have a DPS to use it.
This is why the Limit Break System sucks monkey nuts. No one else can
use their LB because the DPS always have the need to use it, just to be using it.

So if everyone dead, nope, lemme waste LB just because we're going to die.
I wanna use my damn healing break sometimes. D<
They must change the LB system when they have time, as it stands, it's just bad.

In rare occasions when the party make up in a 4 man dungeon is Bard, Bard, Healer, Tank.

You might as well use Tank LB just for kicks and giggles, but yeah its really lame.

GLA/PLD with full Odin gear should use Zantetsuken as LB3 lol... yeah I'll keep dreaming~

The actual honest answer is: No. The tank Limit Break is not ever useful, and no tank should ever even have it on their bar. Stop wasting it.

The only time I ever found use for it was the story mode Garuda fight. Even saving as many stones as we can, we had a lalafell SMN that died to Aerial Blast 80% of the time due to HP. Now, you can say it was his fault for not having enough, maybe due to gear/level, but rather than take that route, I'd occasionally pop the tank LB to get us over the hill, so to speak. Still, lacking the DD LB certainly made the fight last longer, for sure.

But any other time? No. Wasted.

We tend to use it in Coil when the tanks start taking big damage and the healers are running low on mana or there's a lot of other damage to keep up with.
Healer limit break is far worse until they fix the raise animation lock.
Tailoring specific limit breaks to specific classes won't work with a shared limit break bar. Groups will always favor the most powerful ones and pugs will always fight over who gets to use it.
