Those are all great concerns Fen, I am really not sure.

I do know the rifts close after a time. Also, it seems like they start off slowly and build up.

Hopefully they have something up their sleeve so its not like WAR was with PQs.

I know for myself personally Im not a big alt guy so as long as they can make the "max level" stuff interesting ill be alright, but certainly for longevity lets hope theyll have an intelligent solution for the noobie rifts.

In a way its somewhat the opposite of the direction WoW has gone. Were there even any group requiring quests in CATA? I dont know, I didnt make it to the end. Not in the few zones I did though. This is potentially forced grouping.
