How to play Kassadin vs a fed team
So i've been playing Kassadin for several months now and every time I have a feeding botlane I just lose. I admit, I do some mistakes sometimes too but I find it too hard to carry with him, even if I go splitpushing the enemy team does 4v5 easily, my teammates keep dying a lot and our nexus turrets get reached before I even take an inner turret. Most of the games I can't start snowballing too much, cause even if I'm even in my lane if I try to roam my allies die before I even get there. Usually at 20min I'm something like 2/1/1 with 2 finished items and boots. Any advice?
