I main a hunter, and have played iron banner last week to rank 5 with my warlock and can say for a fact how weak they are when their super is active. I was getting killed by last words and mida in a super so fast as I was moving too slow in super which I wasn't used to, I had best hope using landfall and using it in situations Titans would use striker. The subclasses are more balanced than they've ever been. I would just tweak scorch grenades and warlock overshields. I go flawless 3 times a week and have found warlocks to be tediously slow even with high agility (without blink) Titans are fine and hunters are also fine except hunter precision knifes should 1 shot kill with burn time if a scorch grenade can almost kill somebody with little skill. Speed up warlocks, Fix scorch grenades, leave everything else. There's my unbiased opinion from somebody who doesn't bum a single class
