Restrict that to affecting GCDs only and you'll have made Physical Ranged better recipients than all other DPS save Monk and BLM, and Healers better recipients even than physical ranged, just through their bonus damage from traits (20% for Rangers, 30% for healers).

A simple percentile damage bonus is already the easiest thing to balance, because it interacts only with the final product, rather than any of the varied factors in getting there.
I probably should have been clearer ya. My thoughts were more akin to ffxi en spells. A flat potency hit that’s added on independently of your own attack. That would bypass the multiplicative spiral entirely.
