Basically just what the title says, either it auto-adds them on PVP combat or it asks via small pop-up with a yes or no button this would GREATLY increase the world PVP environment and would make alot of us hardcore PVPers happy to not have to search thru the names on spotted enemy in the area to add someone or to look back thru your combat log to make sure you get the name rite blizz doesnt do enough to enrich world PVP and this would go along way to make it alot more fun for us who love it!!!! anyway thats my 2 cents maybee someone else has a better idea fell free to throw them out there.
also yea be nice to be able to disable it in options and auto turned off in an instance or bg includeing WG!! that would drive you nuts im thinking!!! or maybee not
