Also since we are talking about gangs. Gang sparring needs some rewards, this would encourage more people to gang spar. I think the whole point system in gang sparring should be changed to actual spar stats that would carry on instead of it being decreased after each lost. Like a normal spar record, a gang's spar stat would increase if they win and if they lose they will have losing spar record as well but it wont affect the win spar stat W/L.. You can have rewards for gang spar set around 100, 500, 1000... gang spar wins

Rewards: Extra gang sparring member? Gang spar gun skin, etc

Also maybe the gang spar arenas could be redesigned so it's larger to compete.
