Limit Breaks are kind of underwhelming

[ItMe]

Ah, I didn't know that. I'm not into any end-game savage content yet which is where I'm assuming these mechanics are placed?

They're in Ex content too.
For example, they're necessary in fights as recent as Seat of Sacrifice Ex.

I would add to that though at least ( IMO ) that having a boss fight built around a limit break seems stupid and I'd rather see that dropped in place of unique limit breaks, lol.

That might be a valuable mindset going forward, but SQEX has shown they don't wanna change the way the old content functions. They like leaving/preserving older content so I dont think we can expect the raids that require tank LB3 to suddenly lose those parts, and if they did make unique limit breaks they'd def be made with these old requirements in mind so old fights don't become unclearable.
