So is the rare brv damage boost +1 worth the loss of a continuous all the time gain of 1 AC for the scale user?
Right. That's the question I had immediately after reading the errata. Now that I've seen it (only once!

) in play, it's become the central question for my human BRV fighter. (Dwarven BRV Fighters have more incentive to stay with hammer and chain, IMO. I'm ignoring the dwarven case.)
Did I just die from circular logic?
<chuckle>
Scale: +1 AC, 1 less check penalty
Chain: +2 damage part of the time - probably between 1/4 and 1/2 of attacks depending on build and party, more threatening OAs and challenges, greater perceived incentive to attack the defender
It's a real choice. I'd not be surprised if it should be increased by tier, though, like most other damage boosts.
First: The damage boost DOES NOT scale with tier. So we can just throw that out completely. Red herring.
Second: I think the chain armor benefit (+1 or +2 damage if you have THPs)
might happen 33% of the time
in our group. That's in line with
keterys estimate. In our group, the "chain damage benefit" will happen mostly when our warlord uses Commander's Strike -- the THPs simply won't be there by the time my turn comes 'round again (as
DrSpunj pointed out above).
Third: For a non-dwarven BRV fighter, the numbers are stacked against chain armor. The ~33% chance for extra damage is not worth the -1 AC and -1 checks....and it gets worse above Heroic Tier. ...And the headache of having to keep track of when to apply it is - IMO, obviously - a huge strike against it.
1/4 to 1/2 sounds like a very high estimate... but I would find it reasonably worth it if that is the case. I hate things that are so tactically dependent they are either worthless or great... swingy either by dice or circumstance.
I think 50% sounds high. But maybe I'll "play-test" it another gaming session, and see how things shake out.
I find it a little odd that it would be less, to be honest. That implies that the BRV is probably still too good if the enemies are burning through the temp hp every round, because a normal fighter would be dying.
Aw, come on.

Fighters are built to be in the thick of it. It's not at all surprising that a fighter is getting hit nearly every round, and that's for over 4 points of damage, if not for over 8 points of damage.
Auras, on-going damage, etc? Surely your fighter is getting hit with these....
