Like Cyp said, it wouldn't exactly become a gamemode. Though it would be a great addition to some other ones. Support, but might not be a good gamemode idea.
Real good idea, I've seen this on other servers already, and it is really successful on them!! This is a must-need gamemode!
@ParanormalPizza If you're allowed, can you move this thread to suggestions so it is in front? that would be great
Some people just want to watch the server lag. Why not just go on kohi badlion gotpvp parapots lichcraft.... They are just a few I can think of off of the top of my head.
