I'm character level 20. I have a hard and elite bravery bonus streak. I'm VIP and have eaten a tome of greater learning and a tome of greater epic learning.
I decide to do some quest I've never completed before. The quest has has both heroic and epic versions, let's say Beyond the Rift, a Heroic Normal CR 16 quest, Epic Normal CR 21 quest.
What do I miss out on in terms of BB and 1st time xp bonus completion if I do the quest at character lvl 20 for the first time on:
Heroic Normal (16)
Heroic Hard (17)
Heroic Elite (18)
Epic Normal (21)
Epic Hard (22)
Epic Elite (23)
