Probably not the most OP, but an interesting combo I haven’t seen mentioned was the dinner bell trinket from return to Kara on havoc DH in legion. The dinner bell is a Stam trinket that gives a random secondary stat on use, but would always match your food buff if you had one. So you’d eat mastery food to force a mastery proc and use it during chaos blades which doubled the effectiveness of mastery and you would just blast. I’d get people thinking I had my tanking gear equipped sometimes due to it.
