Guild Wars 2

Corvus.5836:

Say a player has completed a dungeon reward track in PvP once the Feature pack has gone live and earned all its rewards, in two weeks when that specific dungeon track is yet again available to progress through, will that player be able to go through the track and earn its rewards again?

i.e. effectively earning that dungeons entire set of weapons and armor sets over a long period of time.

Yup, they said on the ready up that there are repeatable reward tracks(dungeons and regions) and single time ones(balthazar carapace). So if you do the dungeon story you can do the reward track over and over if you want.
