Gameplay- Fizz being hit by cc whilst in Playfull Trickster his E.

I have just played two games of Fizz and in the first game I was mid and I went bot lane to gank Annie the enemy teams sup, I used my q to go onto her and then used my E Playfull Trickster and she then used her Ult while her stun was up I was mid Trickster and I still took the damage and was stunned. This happened twice during that game. The Next game I was Fizz jungle, there was a big teamfight and I tried to get out so I used my E Playfull Trickster and while I was mid E the enemy Galio used his ult and I got taunted while I was mid Playfull Trickster.
