the thing no one ever thinks about with these cheese lanes is how bad the wave clear is. even if you somehow win the early game and start snowballing, youre gonna be in a terrible spot later on. youre minion waves are always going to be crashing into your turret so any time you win a team fight it wont matter. it becomes impossible to take objectives after getting a kill because your waves are never in a good spot. the only way something like taric/leona works is if you have a mid lane pick that can clear waves really fast.
