I don't like the "loser chooses" system any more. IMO the nasty high-damage heavies that showed up last night won their battles more because they could trap lighter opponents in a coffin for half their battles... even though Silent Line added only wide-open stages to the mix. Even Limestone Cave is huge (especially on the vertical).
So I think we'll just switch the stage selector to random and run with whatever God gives us... maybe with do-overs to avoid repeat arenas. Ranged fighters need a boost and I'm hoping that messing up the heavies' arena control is enough to do the trick.
