1. Make PF cross server.
This would make the elaborate, well thought out, and user friendly search interface far more relevant to PF, and reduce wait/gather times. Obviously you'd have to omit server wide searches for Coil still.

2. Change PF Search filter/s
Change the Average item level filter from ("XX" or above) to ("XX" Above OR Below) So that when your searching for a party on PF, you can filter out parties according to your highest avg. item lvl opening up more parties that might be slightly below your current avg. item lvl.

3. Make it so PF can alert you
Implement a method of having PF alert you like duty finder when someone posts an event or has an opening on a job your interested in joining as. For those times your crafting, gathering, doing hunt logs, or dailies without missing an opportunity to jump in on an EX primal or Coil group. Since most people hate/can't use DF for these particular events anyways (with good reason).
