Yea, duel has no place in arena or the game in general.
It’s just simply too good. A CC that is unavoidable, undispellable, ignores trinkets, etc. It’s both the best defensive in the game and the best CC. Something has to give with it. Seeing rogues cc a healer with blind > sap > stun > garrote > duel. Like… lol… come on. This is getting to be a joke.
