Great ideas Funk! Love your player-based events already as it keeps the community engaged when folks are sort of idling about.
I like the concept of the Well of Hostility, but I'm sort of in the same boat as Goddess. I feel like since there's already the Well of Goodwill, it may defeat the purpose of said well. However, I feel like if the concept is worked on more, it may be a good implementation, if doable. I guess we would have to think about how much xp is given, the amount of money that the Well of Hostility will contribute to the Well of Goodwill, etc.
I guess for me, would it A) enable players to want to participate (if there's a lack of participation, doesn't seem like it would be good to implement it) and B) would it contribute anything to the server and its players (if so, how).
