The con to this is I have to upgrade the scale each time a major content patch comes out. In addition its a negative to judge players on a level 80 basis. Such as a well geared level 70 would appear to have "Green" or less then good gear.
The other option is to have it scale with the quality of their gear. For example a fully epiced person has a color of "Purple" no matter what level they are, and a somebody who had 1/2 blues and 1/2 epics would be a "Blue/Purple" color... The con to this is that a level 80 player in all level 70 epics would have a "Purple" colored score which could potentially mislead you.
Anyways, what do you guys think?
