Why Not Make Limit Break Interesting Already?

[Saiah]

Its a shame the tank and healer LB are so situational they barely ever see any use outside of scripted events such as Alexander Prime. Outside of that I only use the tank/healer LB to "remind" DPS that forget it by using it after the last boss of the dungeon is dead.

How could they change the tank and healer LB so that it would be viable to use? What if the LB's were separate for each job? So the tanks and the healers could use theirs freely without sacrficing the damage potential of the DPS LB? Would it disturb the balance of the game too much if tanks were granted a 10 second damage reduction party buff once or twice per dungeon? And the healers be granted a party wide benediction once or twice?*

*Note that im referring to lvl 1 and 2 LB's that you only get in 4 mans.
