Last time I was involved in an on-line game, squadron members (it was a flight sim) had their squadron name, or an abbreviation, pre-pended to their character name. This helped identify who was with whom in game, but also in chat. It certainly helped squadrons enforce their own codes of conduct. Would something like that be of use in ESO PvP? I don't mean tabards. They're not nearly distinctive enough for this.
Ideas?
Please stop making requests for game features. ZOS have enough bad ideas as it is!
