The only Melee that will give you a hard time is a warrior. Rets, rogues, shamans it's pretty fair 1v1s if you're of equal playing skill, you shouldn't be running anything other than focused chaos though you're just shooting yourself in the foot doing that. I've played 49 Destro lock in duels, 2s, 3s, 5s and battleground war games and I'm more than happy to show it as well to anyone that would say otherwise
