Trundle's Pillar Triggering Yasuo's Ult
I just finished playing a Co-op vs AI game as Yasuo where there was a Trundle on the enemy team. Now I'm not sure if this was intended or not but I don't think it is. Anyway, I was just about to end the game when I saw the knock up arrows you get for triggering Yasuo's ult appear as soon as the enemy Trundle used his Pillar. Is that, for any reason, supposed to happen?
