It Says:
* Mission quests send you to replay storyline missions from each campaign.
* Bounty quests dispatch you to kill boss monsters in dungeons, veteran missions, and explorable areas.
* PvP quests challenge you to win battles in various PvP types.
I'm particularly excited about the bounty quests. I hope the first bounty is the famous:

Obviously if the rewards aren't good enough to warrant even doing these tasks then this idea will fall on its face, so I do have some reserve thoughts about it as well.
It is purely speculation on my part, but i hope this gives us a reason to be interested in some pug'ing again. Since these quests are not repeatable = somewhat not farmable in the sense of you have to have 8 players with XXXX build or you can't come.
Does anyone else share my excitement for this new way to play existing content?
