So I'm in a raid with another hunter. He is the same average item level as I am (544). He is finishing boss fights with around 240,000 DPS. While I'm finishing around with 210,000. He has 4 piece set while I don't even have my 2 piece yet. Does having 2 and 4 piece really give you a 40K DPS boost or am I doing something horribly wrong?
