If played perfectly we are top dps by a very small margin. The problem? If you aren't playing perfectly, our dps is below other dps by a slight margin. It's risk/reward. Using GK drops your botd timer to 11 seconds which gives you exactly enough time to do a 4hit combo, but if the target dashes away, knocks you back, becomes invincible, you will lose your buff for another 20-30seconds unless you maintained it for longer than the cooldown, in which case you can reapply.

Basically drg is a lot more fun to play now because we have a 200 potency aoe ocd ability with a cool animation that we can use 3x per minute, and jump can crit up to 4.5k when fully buffed which is very cool. Battle litany is an astounding 15% crit bonus for 20 seconds which is amazing as hell, but long recast. Invaluable for openers.
