Maybe it's just me, but I feel the current Limit Break system... It sucks. The healing Limit break appears to be the most useful (and since Bard has had it's class altered, it's healing is horrible) and the one everyone saves for, which results in almost no one using it.
I personally wish there was something more along of a FF9 Trance set-up with each character. Build up a gauge and go into a cool form or something.
