Latency is only part of the problem, the other part is packet loss. If your dropping packets it doesn't matter how good you are, you aren't going to play to the prime of your ability. It might be a couple milliseconds but it adds up. That could be you missing a shot that you thought you hit, or the game just not registering the shot because your opponent isn't where they should be according to your screen.

Take Overwatch for example. I'm not saying players would jump a gigantic amount of ranks if it all played like a LAN, but I could see Gold players entering low to mid platinum, assuming their individual mechanics were fine.
