The return of The Butcher, for me, is one of Diablo 4's high points. His randomized attacks are surprising, terrifying, and yes, frustrating for an awful lot of players. The good news for those having trouble taking him on is that there does appear to be one fairly reliable way to do it—it's called cheese.
As a number of redditors have pointed out, The Butcher isn't the most agile guy in Sanctuary. He moves with a surprising quickness, but he also has a tendency to get hung up on things. He's also not great at opening doors. In practical terms, what this means is that if you can get him stuck in a doorway, like a one-demon Three Stooges, you can lay a beating on his ass with impunity.
