Right now I feel that HCs are fine in a PVE setting, with the right perks they can be just as devastating as year 1, for example look at imago loop, you can acquire this gun with both firefly and outlaw making it perform the same as Fatebringer. The raid HC is also pretty good with firefly it's only flaw is reloading which can be countered with the use of the cocoon perk. You just have to get use to not spamming your shots, you need to give a little bit of leeway between shots to let the gun 'reset.' In PVP HCs need some love, the loss of accuracy when spamming really hurt them, if you try to aim for the head and spam you hit maybe once, if you give it that leeway and time your shots your dead before you can get a 3rd head shot. So they are kind of operating at a loose loose state right now.
