I would really love if the server was to have PvP and Spleef events weekly. Like for example have a PvP tournament on Wednesday nights at 8 P.M. And then Spleef on Saturday at around 3 P.M. or something of the sort. And the prizes could go life 1st will get "X" amounts of noobz, 2nd will get "X" amount of noobz and so will 3rd.
As for the way the spleef event, it could be run as a 1 v 1 and only the winner will move on to the next round. Once you get the the last 4 people remaining you can put each one at a corner, and start the round. Who ever comes in 1st, 2nd, and 3rd will win.
The for PvP, I think that everybody should have the same kind of armor. During the last PvP event for the 10,000 members, I joined, and I was killing people very easily because I have protection 4 diamond armor
, I know I wasnt the only one using enchanted armor and weapons, but yes I felt cheap
I saw others with no armor, and some with iron or gold, and some people even had dogs that they had spawned with Bone. For the PvP event, if possible your inventory should be cleared, and replaced with the items that will be used, so then everyone will have the same items. This would still be live a "free-for-all" where everyone is in it at the same time.
Lastly for enrollment, maybe there could be a way to sign up for it. Like maybe a Topic for it where people can post that they want to sign up for the event, or maybe a way to sign up in-game. Then enrollment should stop 1 hour before the event, so the people who want to do spleef can have their opponent picked randomly for the other people who signed up.
