hi lace! it's very simple regarding charge reset, FC has 10 sec cooldown, so if you have:

38% CDR, you will gain 1 charge when you FC 3 mobs. 3 x 2 = 6 sec reduction (from rune), then 38% of 10 second is almost 4 sec, thus you can charge again. you don't need exactly 40% cdr due to latency and charge animation, so around 37.5% will do.

next will be 58% cdr, it's the same as above, but you regain 1 charge when you hit 2 mobs.

people saying why you need "Less" cdr now is because blizz make FC to have a maximum of 2 charges, instead of 1. so let say if you have 38% cdr, and you have 0 charge now. with the increase of density, you just need to hit 3 mobs to reset your FC, or 6 mobs to regain 2x charge. unlike patch 2.1.1 you need to charge carefully because no matter how many mobs, you only have 1 charge to use.

so if you have 58% cdr, you regain 2 full charge when you need 4 mobs, which is super easy due to density increase.

Next, fire charge build can only get you to around 44 grift (i am not grift kaki so that's estimation). anyway, if you want to go high grift level, physical charge is the way to go because it clears the mob so fast that you have plenty of time to kill RG, however with a few condition.

physical charge is better for clearing mobs because your battle rage - bloodshed is physical rune. so your physical element bonus is added to bloodshed, in short you have much higher aoe damage than fire.

with physical charge, you are very dependant on RNG.. especially on GRG, physical charge are fishing for guardian that spawns adds, or duplicate itself, like the rockman, so you can utilise your aoe to burst the boss down.

Fire can only go so far but is more reliable on lower 40+ (fire build is for more single target power). if you want to get as close to 50 as possible, then physical is the way to go.

edit: for t6 clears, use toxin, pain enhancer, trap, just charge charge charge and let your DOT do the damage.. physical build too, because PE is physical, toxin bonus damage is multiplicative, have fun!

ya cool down reduction

try not to ish.. get 38%. dont alang alang, hehe.

bro you have maximus and fire amulet, choose battering ram as your FC rune.
