Bob Dole really wants to have a raven's bite build, but he can't make it work with a b12 because b12's give you more attack cd. It's not like it's unusuable, but it's just so bloody terrible compared to anything that's in the meta. 4 coin cost +20% more cd with a b12 makes this a dumpster fire. You can't even wear a shield with it. You need 60 coins just to start a round of attacks, meanwhile, other builds can beat you up with like 6 coins.
It's not like this build would even be the meta, but because there is no good axes besides b12, the attack doesn't even get to see the light of day. It doesn't get to shine

I mean, look at the absolute state of axes.
Bronze Sword does 90 base damage.
Fyrdsman's Sword does 100 base damage.
Hirdsman's Sword does 125 base damage.
Cutblade does 135 base damage.
Axes
Stone Axe does 30 base damage.
Metal Axe does 45 base damage.
Butcher's Cleaver does 45 base damage.
Woodsman's Axe does 55 base damage.
Battleaxe of the Twelfth Bay does 150 base damage.
Even bronze swords beat out the axes GREATLY... and hirdsman doesn't even have a cooldown... and you can use a shield with it. Where is the justice for axes?!
Don't you know axes and spears were historically used in warfare far more than swords? Swords were just a pathetic sidearm, unless we are talking about greatswords, but those were not even widely used.
