Medieval is a greatly underappreciated theme, both game mode wise and detail wise. You guys remember Helms deep V2? That map was crazy good looking! There was a time, long ago, maybe three or four years ago, when I used to play on a medieval custom maps server that was a ton of fun. It had, like, arena, payload, king of the hill: just a ton of awesome maps. Then, out of nowhere, it shut down, and now the only medieval servers that ever have players are fucking 24/7 degroot servers with like bots for half the players. I would kill to get to see a server with tons of awesome medieval mode maps.
(Note: The only two classes in medieval that have no melee unlocks are Pyro and Engineer. While the Gas Passer seems like a totally fair weapon in this mode, it remains blacklisted. It's unfortunate to see the Pyro still having a pretty pathetic roll in medieval.
