I did well bot lane and was decently fed and in good carrying position for teamfights, but every teamfight the akali and the garen would dive straight through the team and right for me. So I would basically run away every fight and the akali would always catch me and kill me.
I don't know what I was supposed to do differently.
Both teams have weak comps imo. What you're supposed to do is keep your distance, target whoever is closest to you to make them get back. As graves you have a few escape options...you should use your smoke grenade in combination with a flash or something.
unfortunately if you're an ad carry you're kinda at the mercy of your team to peel for you for you to function in teamfights. best to keep your distance until you see the divers use some cd's on your other teammates, though it'd be unlikely with 3 people gunning for you.
