I think that there needs to be some tweaking done to make the ladder rankings more relevant and interesting when the next installment of HSG comes out, and when the website has more traffic coming through (competition/tournaments).

1st I think that a player should be able to challenge whoever he wants rather than a player that is ranked 5 spots ahead or below the challenger.

2ndly, I don't think people's records should be erased from the ladder if they don't play for awhile. I noticed that 14 players from the OT2 ladder were erased after me and welpitsme played our match.
