Who decides ranked match schemes?

I recently purchased the Nintendo DS version of WOW:2, and I have to say this a great game. I've noticed that when you play "ranked" deathmatches, the scheme seems to be different every time. Who or what decides on this scheme? I only asked because I just played a game with no starting weapons whatsoever! The only object you got that dealt any damage was a couple of blowtorches. Needless the say, the only possible way to win the match was to hope that sudden death took your opponents before you. Not very fun at all, to say the least.

Unfortunately the ranked scheme is chosen at random on the DS version and some of the schemes are just not suitable or fun. At least in non ranked games, you can vote for the scheme.
