When should I use Berserker Charge?

My usual game with Wolverine is either cr.l (or dive kick), m, h, s, j.m. j.m, j.h, drill claw, dive kick, h:
-Berserker Barrage, Hyper
-s, j.m, j.m, j.h, drill claw, Fatal Claw

I see people use Berserker Charge at times, but when should I use it?

i’m not really sure what you’re trying to say here. your “usual game with wolverine” is a combo?

you use it when you want to keep your unassisted bereserker slashes/barrages safe on block and maintain frame advantage, or when you want to combo from them(slashes/barrages) if they happen to hit. so when you see people use berserker charge on stream or whatever, 99% of the time it’s in one of those situations. other than that, you’ll sometimes see it used in combination with xfactor–because xfactor wolvie + charge = free IOH combos–and you’ll sometimes see it due to a botched wavedash attempt.

something you won’t see, though(and is something i like to do if the conditions are right) is: invulnerable tornado claw cc assist, b.charge cancel first hit(before feet leave ground) into a full slash loop.
