Limit breaks are incredibly boring; even more so being that they are available to only one person (usually melee dps). Why not offer everyone the opportunity to have their own limit break gauge? In something like FF7, I always looked forward to my limit breaks charging up because they were all unique, useful, and looked cool! I think SE did a really good job on meteor and the melee dps one, however we should all be able to have the opportunity to pull something flashy and useful out during a battle.
