Question about an enchant

Hello! today I saw a combat rogue using Black Magic on his off-hand weapon, is this bis? I know on retail back in 3.3 it was the best, but i'm not sure on warmane, I still use 2x berserking. Which is better, 2x berserking, or 1 berserking/black magic?

Thanks! <3

Who told you that Black Magic was best on Combat at any point in the game?

Just go double Berserking, mate.
