If it makes you feel any better Butcher is actually really fuckin hard on heroic, because hes a ridiculous gear check. Like, 13k is kinda low but 99.99999% sure that wiping on butcher is not your fault lol. AND you’re combat. WHICH ISN’T A BAD THING. It just means your butcher dps is gonna be low, because combat has d@ cleave. but the cleave helps you on a lot of other fights. Just keep at it friend, you’ll get there 🙂
Not to mention that itemization is shitty for everyone this raid because blizzard seems to randomly assign stats in the first raid and then refines from there.
