Please Riot, Fix Pathing
You're low on health, running away from an enemy champion, constantly running back towards your turrets. Everything seems to be alright, you're going to make it back to the turret! They surely won't chase you through there. Then suddenly, while you're clicking frantically to move towards that turret, you walk backwards into the enemy!
You have been slain!
You stop and wonder for a second, "HOW DID I MOVE BACKWARDS? WHAT THE HECK?"
You did nothing wrong. You did not walk backwards on your own. It was a bug in the system, a problem with pathing. Pathing is a broken mechanic. While it usually works, that's just not good enough. Please, I beg you Riot, fix pathing. One mistake can make or break a game.
