Do you happen to have a link to that post? I'd like to see the math involved.
Ahahaha... man. We're on thread 9 now... digging up those posts would require wading through hundreds of responses. That's why we condensed the tested info we had into a Guide that we post at the beginning of each new thread. IIRC, I think it might have been in thread 6 or 7 when we discovered that the weapon spec perks are kinda lame. Please don't make me do this...

It's bad enough that I took over for Cheshyr as the lead "thread monkey" over there.

Please tell me that a link to the latest one we have going is good enough for you.

There are links at the top of the threads that back-link to the earlier ones we've had, so you can visit #9 and find out where the other ones are with one click.

PS Agreed that mods could change the landscape, as far as these kinds of perks go. I am planning on making one myself that would alter armor values and skills of NPCs to make Bonebreaker more relevant, and perhaps even necessary at high levels and master difficulty. It may be tough to mod the other weapon spec perks, though... hopefully the CK will have potent enough functionality to let me get into the guts of the damage calculations and let the bleed and crit perks scale with skill/enchants/smithing.
