I have been levelling my tanks and healers recently and I have noticed that a large majority of the DPS that I run with don't use Limit Breaks on bosses anymore. And the ones who do, usually leave it until it is too late and the boss is within 2-3% or they die during the Limit Break usage.
I have always made sure to use Limit Break whenever it is available especially when on Melee. So what happened to the Limit Break usage?
