mhm, I've never played much DotA on Bnet (I play in Garena) so haven't had too many problems with SO mode... Mainly because its rarely if EVER used in Garena pubs- when someone ragequits, their team is usually left to die, or we just RMK if it's still rather early.
I think it's because of the ladder thing, makes all the n00bs not want to loose at all, and apparently they know switching means the winning team loses, so yeah, fail -SO glad nobody is using it over here.
Anyways, here is a reply to examplify what happens when people fuck up and switch
