I just had a game like this the other day. I was jinx, and my support was Janna. Our play styles did NOT mesh and we were bitching at each other early on. We kept playing it out though, and we ended up carrying HARD. She had 20 stacks on mejais and I wasl ike 12-2 or 12-3. I literally said I take it back, I don't hate you Janna.
And then my support Lux started carrying.
