[GAMEPLAY] Shaco not revealed by Azir turret

I don't have any video or photos, but I was in a ranked game as Azir with a Shaco on the other team. With the turret resurrected, I was purposefully standing close to it waiting for Shaco to dive so I could Zhonya's, but he didn't show up. He just popped out of thin air and assassinated me. ultimately losing the game, this could have provided my team with pushing power to take an inhibitor or even nexus towers, but because he was about to stealth behind me, my team had to back away and leave.

If anyone has input great.
