Some advice desired.

Hey guys,

I like to play AP Malphite. Sometimes it's hard to decide if I need to peel, dive their backline or just backoff. I'd like some advice for the situation in the video.

In the beginning I was going to try and flank. But then Jhin ulted and I turned around. After Ziggs ulted the enemy backline was pretty low. I could have tried for Flash+R on Jhin. But I wasn't sure about the ult range and damage because he got a Karma shield. In my opinion it wouldn't be worth to ult poppy when she was going for our Ori. Jhin had a Karma shield before I ulted him. I think he would have if he had not gotten a lvl up. Could i have done anything better from a tactical point of view?
