Discrepancies to point out

[Infiltrator]

I think this is a bug and not a feature:

Everyone knows that once you reach 0 rage, your mana starts regenerating rapidly.

The problem is, once you get Bloodlust (which makes you always have a minimum rage amount based on your max rage) you lose the ability to regenerate mana quickly since you're never at 0 rage in adventure mode.

I think that in the next patch, they should allow mana to regen quickly once you reach your minimum rage threshold to reduce the tedious amounts of time you have to sit out and wait for your mana to regenerate.
