Here's what's bugging me: the upkeep does bugger all once teambalance has run its course, since by then you know who's going to win and who's going to lose.
So essentially, people who're willing to metagame can upkeep a plated charger, plate, throwing lances and all that by just spawning naked when they're on the losing team. Which cements them being the losing team.
I'd rework it so that you pay upkeep anyway, regardless of win/loss, but with repair costs about 35% of what they're now, because upkeep has sort of failed as a mechanic if it enables people on one team to play the old crpg... and people on the other play with lowend gear.
