Please help me.

I will preface that I'm in s2. That said, what can I do to protect myself against assassins when I can't count on my teamates to peel/defend me and when GA is on CD?

GA has a 5 minute CD, meaning that assassins can dive me with their less than one minute CD. I can't rely on my teamates to peel for me/defend me. They don't even try. They just shrug their shoulders and dive the enemy backline saying "That's what assassins do."

So I ask again, what can I do to defend/protect myself from assassins when GA is on CD and my teamates don't even try to help me in solo queue?

PS: Don't say change rolls. I don't enjoy playing tanks.
