Doubt it would really work in reality. If it was a base primarily for newer gangs, then what stops one of the main gangs to create a new gang that is an ally, and then just base at the 500 hour base and control it for a relatively uncontested 500 hours before the next gang does the same.
Nothing stopping gangs from recruiting people from the main gangs, or players with strong guns which would defeat the purpose.

Having a base that you can only use the mpx gun in wouldn't work either as say a gang manages to get 500 hours then when they have to base in the normal bases where there is no even advantage they will be in the same situation as they were at 0 hours where they can't compete with those gangs with better guns.



To me, the only way to really make basing more competitive is to stop adding more gang rewards. New gang rewards kept being added (which I was against) which gives more things for those high up gangs (20k+ hours) to keep basing towards. If basing hours had a cut offpoint like at 10k hours then a lot of those gangs would probably retire which gives other gangs a chance to fight for hours or start a new gang.
But now since there is a 50k gang reward you probably won't see those gangs quit for another 3-5 years
