So this probably sounds like a rant, but there's a game-breaking "feature" on Summoner's Rift where the map changes elevation at the River and the steps of fountain.
This has cost me tons of kills and gotten me killed so many times I've lost count, and it needs to be addressed.
I understand it's great to have a good looking map, but it needs to be functional too.
I've posted about it before, but it's just such a big problem, and it feels like nobody at Riot is doing ANYTHING about it.
