1. Increase player min requirements to be 200hrs played on Olympus servers and players must have joined Olympus servers 30+days ago.
2. Players on the roster need to be in the participating gang for at least 1 week leading up to the event. Preferably longer like 30days or maybe from the time they signed up they need to remain in the participating gang.
It's gang wars so it should be actual gang members fighting this not random hired guns fighting on another gangs behalf. Like one could easily 'hire' good players/shooters and pay them 10-20m each to fight for their gang in this and they'd probably win. People do similar with their conquest rosters for the day..
One could pay 100-150m to stack their roster/ensure the win and they'd get the special tag, billboard, gang uniform, etc.
