There is no predicting which players will quit other than to know that all players will quit. And I get that people lose their connections. I used to lose them regularly. But when a player dumps a ball in the lake and writes "F**k this" in the chat window before quitting, I bet it wasn't his internet connection.
Just nearly finished a CTTH blitz game, except all 3 players quit, just as soon as they realized they weren't going to win.
They were zerox518, followed by ddouglas533, followed by adamchap. And guess who gets the same negative impact to their quit rate? Me.
I'm finished with multiplayer games. I might as well be playing this game offline for all the interactivity I can look forward to.
