This is a spin-off from this discussion: https://forums.cardhunter.com/threads/pvp-event-idea-guild-wars.5194/ I thought I'd try something simpler and more automated. First we'd need a few feature: I had completely forgotten that conversation when I posted this: This is how you would prove that a scenario is valid: the game would allow players to lock the scenario before posting it to the forums, and when the scenario is played the API will report who locked it along with scenario name, who played, who won, and timestamp. With that (and some help from Farbs' stats site) we can do guild raiding: When a guild principle beats a map labeled [RAID] that they themself locked, that map becomes the official raid map for that guild. When a guild member beats their own guild's raid map, they become their guild's Champion, replacing the previous Champion. When a guild Champion beats another guild's raid map, the Champion's guild earns points against that other guild. The stats site already tracks guild principles and members, so it wouldn't be too hard to also track current raid maps and champions. Only having one champion per guild is to slow down the big guilds (they'll spend half their time reclaiming the champion status). All the stuff with beating your own map is to prove that it's not impossible or even too difficult. (It can be really devious, but that's fine: you're supposed to booby trap your guild hall). There is one possible way for a guild leader to cheat with this, and if that happens will have to change it so all maps are locked by the Raid Ref.
