I usually, when levelling my BvCs, get them grushed to hell, do dias until 60, level in baal runs until 76 and then mule the gear. And no, I do not use ANY gear until then, except some randoms that I might find.
However sometimes I also simply mule all the gear and equip them when I can, very nice to have such high life when levelling.
As for skills, I did this with my newest and most successful BvC:
20 axe mastery
6 increased speed
6 nat res
