You can barely start a game now without a leaver. Custom games has completely failed in SC2. The 30 second countdown is just too long for people who want to start a game, and is too forced for people who just joined a game.
The fact that the countdown DOESN'T stop is irritating and dumbfoundingly stupid. What was Blizzard even thinking? Do they think at all?
It's pretty clear to me now that they fired their old Battle.net team or they left Blizzard for ArenaNet, and hired a bunch of xBox Live coders to do a half assed job.
I've gone to games that just cannot be played. Storm fo the Imperial Sanctum for instance never really starts because there is always one game to join (no Easy Mode or anything) and whenever the guy starts, you can't cancel and someone always leaves during the count down. Other games where it's bigger than 2v2, someone always leaves while counting down from 30 seconds. It's ridiculous bull that this is going on. I hope patch 1.1 does a complete redo of the custom game arena because it simply doesn't work right now.
