I know its a casual tourney but since the game setup is set to default tdm without perk restriction so I must say this:-
nub launcher nade fest FTW!!!!

I understand the purpose of breaking up ppl into team randomly. Please give the new and curious ppl a breathing chance. Bring your dota friends to play this game, spread the words!!! because now dota tourney is all about clan matches, newcomers can't budge in unless they have a uber skillz or join a decent clan and mix in with their top tier lineup. I believe pro tourney will be scheduled after this even if this event is somewhat unsuccessful.

Search & Destroy mode is the de facto format for CoD4 tourney but personally I like Sabotage
