There is a content gap that dailies fill independent of grouping issues.
This.
Also bear in mind that Bravery Bonus is something of a red herring:
If you ran the Heroic version of the epic chains (Like Phiarlan Carnival) you are no longer eligible for BB in the Epic versions (unless this mechanic has been changed, AFAIK, it has not been).
That kills Carnival and Sands right there.
Likewise, for those people who are Hella Pro, knocking out EE at level for BB might not be a problem, but as a less invested player, I look and say:
"Well, I could probably get this done... But I could run it twice normal or Hard then Normal for more XP in Less time. Fuck the BB."
It's still faster for me to run WizKing twice true Solo than to try to hit it EBB first time (which i won't get, because it's part of the Lvl 12 Heroic cycle).
After that, you're back to grinding again. S/R/E and challenges (also a crap shoot because of RNG) are stop gaps measures at best.
Challenges are also "First Time, best Time" XP because of their stars system. Half of them are still broken so they can't be completed for Max XP or rewards anyway.
Asheras was right when he said BB and adventure areas should reset on ER.
Why that hasn't happened is a mystery to me.
