I dont mind either "Group limit break or individual limit break" , but i agree that its feels bland and could use some updates.
If its become individual limit break though, i want the system to force "everyone" in the party to need to use it at some point in the fight.
Most of the DPS right now are refuse to LB because of FFlogs, reason is they lose slightly of damage...
(and ppl says fflogs/act dont affect the game... but strongly encourage player to not do their job properly for self benefits, including uptime and not avoiding mechanics)
