The list of teams in the database looks very much like the original list of team compositions in the dungeonbowl ruleset. I'm fairly certain that it will have to change, partially to allow more of the new (GW-sanctioned) races to be added, but principally because there are no minotaur, troll, treeman, or kroxigor teams anymore (not sure there was ever a kroxigor team either...). These players now only appear within other teams, so it makes little sense to have them listed separately, unless big guys are removed from team lists completely and included only in specific teams. While this would solve the current argument over the deathroller (

) I can't see it happening (as I don't expect that they'll be changing the current 3 teams that drastically).
Perhaps Cyanide will replace these defunct races with new races who aren't represented yet? This would probably be the simplest solution.
