FWIW, the problem now with BRV is...you'll not often get to use the +1(or +2) damage to your attacks.
Before, you could rely on getting THP from getting hit before your turn. Your AC was low (chain), and you are the defender, so you are *bound* to get hit during that first round of combat, often before you get to go. After you were hit, you got THPs, and thus when you attacked, got a +1(or +2, with hammers) damage. That was the whole point of going with chain and not tanking up to plate.
Now, you first need to hit to get the THPs.....and by the time your turn comes around again, it's likely (see above) that you'll have been hit, and your THPs are gone. Thus no +1(or +2) damage.
Add to that the fact that you must *hit* to get THPs, thus using a low proficiency weapon (re: hammer) is stupid.
So before, hammer and chain was the way to go. Now? Plate and longsword. Forget the damage bonus: you'll rarely get it.
