There's almost no point of basing now besides gang specific rewards (hats ect) because the rate of gp is so low.
You probably get around 10 gp in a base per hour (unless it's bank which is a full time war zone) even then its nothing compared to how it used to be.
So yeah give back the old system or think of something better if y'all are so keen on this kill=gp thing. Because it doesn't work and it will never work the way it is now
