This would be really really fun in my opinion and might attract some players. I believe God and Titan ranks should be able to host events such as Sumo, 1v1's, Last man standing, infection, red rover, and waterdrop, with maybe a 4-5 hour break in between each host.
No support. Mineverse isn't really big enough for an arena pvp type addition. There just isn't en0ugh of a playerbase.
