The idea came to me when talking with a CM, informing me about the tier 6 sets.
At some point the CM called them Guild Uniforms...
And this way i thought.... Why not Guild Uniforms? But then the individuality of each person...
But there is a way... Coat of Arms! They could applied to the main body of the character or at a one of the upper corners... And there are plenty, almost ready to use, coat of arms at your data base... (See IO!!!)
