I really like the PB format. I think it lends itself to the way most people play/ choose to play.
There are parts that can be soloed and as you go further the more people are needed.
The doing boxes are nice and I love the addition of new content, it is really hard to find time to do a 2 hour box.
Then trying to find people that have that time free or commitment also.
Eval idea of having the tier is nice but I don't think thats possible.
IMO PB system is how all quest should be, not a grind/ farmfest.

Eh its content wether or not Im going to be thrilled by it is eclipsed by the fact that Rarebit is pushing out alot of it lately.
If I have prefference though its mission based solo quests. I have no idea how you scale these to be a challenge at all maybe just a huge time sick but I would like to see something like the Jedi quests in SWG someday.
