The results aren't pretty...
While this is not really something that we want to encourage, players do have the choice to play the game in the way they want. We can’t force those players to be all-inclusive in who they invite to the parties they create, and to be honest, doing so would probably make people even more unhappy than they are now, and lead to a lot of undesirable behavior.
tldr; people are going to do this anyway, we dont't want to encourage it, but we can't control how people react to content.
As for ascended gear, to reiterate what Chris has said (https://forum-en.gui...Chris-Whiteside), it’s not intended as a treadmill, but rather as a tier of rewards that can help bridge the gap between Exotics (a few hours of effort to acquire a piece) and Legendaries (hundreds of hours of effort to acquire one). They’re currently only available in the Fractals of the Mist Dungeon, but we’re going to be adding new ways to acquire them, both inside of WvW as well as elsewhere in PvE.
tldr; we want everyone to experience content... Now watch as I reference Whiteside's post without telling you why Ascended gear needed to have more stats than Exotic/Current Legendaries, and tell you there is no gear treadmill...
