Dragon hunter crossbow currently costs around 100M+ more than an ACB and ACB currently out dps's DHCB against kbd and ACB has a special attack bar. possibly could use adjustment or buff in DHCB.
You're just having bad luck. I have tried both on KBD and it seems that DHCB DID worked out. It doesn't need to get a nerf/buff in my opinion. When I get outdpsed by a dragon scimitar vs my rapier I won't call out a nerf/buff also. You just had bad luck at the moment, buddy.
Pretty much what everyone else has said. The DHCB does not need a buff as it’s already strong versus dragons for the price that you pay for. Just unlucky hits, is all.
