Might be a good idea to change the rules for claiming turfs. Many turfs remain unclaimed. The lower gangs don't claim them as they just get knocked off as soon as they do and can't reclaim them. There is no incentive for them to try and hold a turf. Maybe change the rules so that if they claim and get knocked off they can reclaim it.
That is a distinct possibility, however, I should hope that your gang cannot be beaten by every other gang in the game!!!!!!!!!!!!!!!
to be totally fair here odds are there are more bigger gangs than yours so you could just constantly be knocked off. Not a fact of losing to everyone just people who want turfs which are almost always big named gangs
