Seperate Limit Breaks for everyone during all content.

Basically you as an individual can level up a personal limit gauge to lv 2 and no higher. The effects are different based on roles.

Healers level 1 a strong group heal that is near instant cast. Level 2 a single target quick cast resurrection on the target of your choice.

Tanks: level 1, a self targeting high damage negating buff, like a shield. level 2 a strong DPS like damaging move that has some kind of benefit that falls in line with tanking.

DPS: These remain largely the same as they are now.
