[Suggestion] Much has been done in SWL to equalize multi-hit abilities with single-hit abilities to maintain balance with proc effects. In the Secret World, multi-hit abilities had an inherent advantage in triggering procs because each hit per second had a chance to do so, even when a proc event was limited to occurring once per second. Thankfully, this was changed in Secret World Legends so that no number of hits per second count as an advantage in triggering a proc. And since many effects are limited to being triggered once per second, even Channeled abilities work just as well as any other ability with procs such as the Ashes of Crushed Cities.
This is not true for Flame-Wreathed, Plasma-Forged, and Efficiency. Abilities with cast times greater than one second can only proc these effects once per ability cast, making any build with such abilities trying to make the most of these effects at a significant disadvantage. Considering all other proc effects were normalized to work the same way no matter the type of ability used, there’s no reason abilities with cast times should be penalized for using Flame-Wreathed, Plasma-Forged, and Efficiency when there’d be no advantage to be had. If these abilities work equally well with effects like the Ashes of Crushed Cities, there’s no reason they cannot perform likewise with these three effects.
