It's really weird that DRG has the longest combos but is also punished more for disengaging than some other melees. Making Piercing Talon not interrupt combos would already help; it's not like DRGs will suddenly start spamming it with its low potency.
It's just so you have something to do to keep uptime that's not a dps loss.
Having a skill that's a dps loss in most scenarios over doing nothing is like a slap in the face.
