Is this a hack or BRD OP issue?

Not hack, just good old bard burst. Takes all of 2 seconds to pull off once the appropriate dots are on you. That last skill you got hit with is most likely sidewinder.

those where not used, i gave you the full log of 100% hp to 0.
I am confused how much you can use when most jobs are on a global cooldown, this would be the equivalent of giving cure, cure II, medica, medica II, an regen their own cast timers, along with swiftcast +spell not effecting any of those "GC" Why is this allowed?
