Very unique and interesting suggestion! Also very, very hard. I originally started modding with PvP servers before going to a standard server like this one, and we were well on our way to some awesome automated pvp gametypes in game, but the coding fort his game makes it very hard to get everything to work how you want it. Once we've got a few more members and theres an interest shown in some PvP features, we will definitely be throwing in as many as we can, although locking classes out of certain maps is pretty much impossible . The spectator mode and 64 players was indeed originally created for PvP purposes, so I would love to utilize them as much as possible in the future
