Then you would have people purposely not upgrading power, but upgrading initiative and high end ninjas. No matter what you can game the system. The "only" reason to stay low level is sage, and thats for older servers too. You get better TI/Wanted missions/ list could go on for a while, too lazy to list everything. Sure all those advanced refines are good. On older servers though I do agree a power based bracket is probably better, but its really not a big difference either way.
