I’m not only concerned about the fact that there is no measurable metric to sort RPers by, but by the automatic nature of it. If I get grouped with one group of players for PvE, by virtue of my previous activities, if I suddenly feel like switching gears in the open world that’s going to be very difficult. What if my world completer wants to go butt heads against some events in Orr? I’m going to be sorted with people who are more interested in exploring, and those events are going to be a whole lot harder to have any fun doing when all of the experienced PvErs have been sorted out separately from me.
Flipping a tag before zoning into a map would allow players some amount of control over the game experience they want to have, while still letting you sort people into maps for maximum population, -and- giving roleplayers a way to maintain the way -they- like to play the game (when you have been much better than many MMO devs in supporting your RP community).
