What about a title for people who spend a lot of time in PUGs? Connect it to the number of different people you have completed missions with in pve or battled with in pvp.
1000
5000
10000
25000
It might get a few people to drop a hero or two and pick up some outside help, or even seeing more experienced people helping others out with low level missions.
There are lots of friendly people out there and it would be great to recognize them.
