Yeah, I agree. I guess at this point I feel pretty satisfied with what I've got here. I'm not going to go hunting for the Minotaur Greathammer, since I had seen that before and it just sounds too power gamy, and this character would need an exotic weapon proficiency to even use it, something I don't have the feat slots to use. And I'm not going to multi-class fighter so I can get it. I wanted something I could stick with that felt more cohesive than the vanilla barbarian, and allowed me to stay viable late game compared to the other characters in our party.
One question though, where do you get the 140% chance to threaten a critical? Is there something about the mechanics I'm not understanding here? If you roll your crit threat range on the dice you re-roll, and if you hit, you land the crit, right?
I understand how you feel, but I guess in my mind, it's a bit of a far stretch to say that an axe would splatter an enemy. Perhaps one day I'll try to tackle a "Sunderbarian". For the time being, I'd like to show clubs and maces a little much needed love.
EDIT: Oh, um, that isn't that stupid great hammer. Sheesh, is that really WotC official? Who created that abomination?
