Quelling strikes itself needs no "buff" like increased duration. Its recast needs to be shortened.

Oh and dear fellow Bards: If you see a tank struggles with keeping hate, when you give each mob you see enemas of wood and iron, how about you tick down a notch? No you wont slow down the run, a tank losing hate to an over motivated bard means more MP strain on the healers, this leads to wipes and slowdowns in extreme cases.

oh and in low levels, tanking against bards IS hard, you miss a lot of skills. think of the tanks


How to lose hate for DPS:
Slow down your ability rotation for a few seconds.
