Force Feedback: Chance for Recharge+ Question

I have a quick question that is related. I have my FF proc in footstomp on my ss/shield. Does the chance to proc only happen when KB is applied to the mob (66.7% chance for FS) or every enemy hit?

It procs a lot enough when Im soloing against spawns set for eight to bring my recharge average up from 87.5% to permahasten levels, 105%+.

For the OP, one other thing to be aware of if your shockwave is up faster than the 5 seconds, it will not reproc on the next mob as it wont stack, could be a slight annoyance factor wasting the recharge from the second SW.

I have this proc slotted in one attack each for four of my toons. Footstomp on my SS brute and tanker, Dragon's Tail for my MA scrapper, and Thunder Strike on my Elec/Elec scrapper.

I'd say that it's potentially worthwhile for the recharge benefits if you already have a decent amount of recharge for that power. I see it proc often enough on the MA scrapper and the SS tanker to make it worth it for me, because their builds work out with the timing being about perfect for the suppression to fade and the proc to check again. It's debatable where the Elec scrapper and SS brute are concerned, and I might remove it from them. I find it most useful when soloing spawns for six to eight players, as there are enough targets to sufficiently bump up the odds of it firing each time.

I certainly wouldn't plan an entire build around getting these though, and definitely not in every attack that can take them. Pick one relatively quick recharging AoE or PBAoE that you plan on using frequently, and then only if you plan on taking on big groups of enemies so you're hitting the max number of targets with that power on a regular basis.
