Either the Sleep trait needs to just not work in PvP, or we need to go the Swiftcast route and apply large magic damage reduction during and just after the sleep debuff. I think we can agree that sleep should be smartly-applied CC like in PvE, not just an easy way to set up your GC's orbital kinetic weapon spam.

For those who feel the Bard adrenaline attack should be different, I'll remind you that Physical Ranged DPS is getting their own set of Limit Breaks in 3.0, so they'll presumably get a new Adrenaline attack as well.
