Still, almost a half of WLN players would be kicked a ton.
Think of it like this:
You are a regular wonderland player who lives in LA. You try to join LA JB but you can't because the server is full. Now, you have to play on a server with higher ping.
Now, on the same server, you have 8 dudes with 200+ ping who could play on our SG servers, but have no incentive as no one joins it because they can just join LA. The facestab the warden every round.
Another example:
You're playing Deathrun. You're the Death. You have one last trap, and one last scout. The scout runs across it and you catch him. But, just then, that scout fazes through a wall and wins the game. You check the ping. 600+ God damn ping.
If that doesn't convince you, I have dozens of examples.
