Vote kick systems should really punish unfair kicks much more severely than they do (i.e., lengthy account suspensions if GMs determine it was unjustified); but I won't go too far down that path today.

What I would really, truly, like to see is a change to majority is required to kick players from the group. In a 4-player dungeon, as we all know, only two players are required to vote yes for the kick. It would be really nice to see it increased to three, otherwise it fails.
