Make Yasou Windwall not block ultimate ability

I personally think that Yasou wind wall shouldn't block ultimate abilities since ultimate abilities have long cooldown while Yasou windwall is short. I personally get frustrated when Yasou block my ultimate ability, because I waited 2 mins for it to go off cooldown, only to be blocked by 20-second cooldown ability. For example, I was playing Ornn and I was laning against Yasou and once we both got to level 6, I started losing lane really hard since Yas can ult me, but I can't ult Yasou back.Yas had basically made me a useless champion since I couldn't engage in team fights unless he wasted his wind wall, which was rarely. The problem with Yasou wind wall blocking ultimate abilities is that the ultimates abilities have slow animation speed, which will require less reaction time.
