Dwarf Ax: "This axe is too large to be used in one hand without the special training that all dwarven warriors receive."
I would love to see Dwarven Axes live up to their name and description. The in game graphics really don't look all that large - no larger than the Battle Axe that anyone with martial weapons can us.
But my main issue with Dwarven Axes is they are not a great weapon for Dwarves to use. They are not much better than the plain old battle axe - slightly larger damage die and the ability to do glancing blows. But honestly glancing blows aren't that much of a gain unless you take the two handed chain of feats. and if you gonna do that, you are better off using a great axe. Otherwise, if you want to use a shield, you really need to take the shield chain of feats as well and that's a lot of feats, especially for a Dwarven Paly.
Some changes I think are needed for the Dwarven axe:
1. Give Dwarves a deity that improves their ability to use their Race's signature weapon
2. Give the Dwarven Axe 19-20 crit range - its supposed to be a big weapon! - if that seems over powered since it has a d10 die, the die could be reduced to d8, but personally, I think it should be d10. It is a special weapon, after all.
