If you can next, Heal Thyself seems to be worth taking a more serious look at. I'm rather enjoying it so far, but I'm wanting to compare it with something like the Striking Light mod to made a decision between the two.
the idea of it is awesome however getting charged with light in pvp is only possible with orbs of light which are quite rare. You either have to get a double kill with the same weapon or wait for a super and either way you spec your entire build around getting half of a grenade back only a few times.
I showed this in my last video if you'd like to see more clearly, but for now we can choose between 3 mods that charge us to equip on a separate piece of armor. 1: charge on orb pick up. 2: charge on finisher but use 10% super. 3: charge on shield break with matching element.
I dont think the mod generates a fixed percentage of your grenade. I run a build with phoenix protocol (double grenade charges) to keep my teammates alive during group content. I got 71 discipline. If I toss both, my grenade energy is up to roughly 90%. The normal cooldown for a grenade is at 45 seconds at this point so I believe it shaves of a set amount of seconds off your grenade cooldown. Have you tried testing it with higher discipline?
Does this work well with charge harvester at the sacrifice of a charged with light level increase? Might work well with a shotgun or fusion with demolitionist too.
