I mean, not that my opinion matters, but the scoreboard currently makes no sense, since an established way to get to the top is do doubles/triples games with 1 or two people you communicate really well with, against 2 or 3 disorganized random dudes, preferably on completely odd-ball maps.
I play all my games single, in 5-6 player games. This means the scoreboard has not a whole lot of meaning to me.
Ideally I'd like to compare myself to other players who play single against 5-6 opponents on non-ridiculous maps.

Anyway, by all means KEEP the current list, but it should be relatively easy to compile a report-script that makes rankings for a bunch of other formats.
