The solution is so simple, it's funny.

Adds active and passive combat skills to the race or species skill line.

For example:

Argonians deploy their claws and do a lot of damage in melee attacks.

The Nords have the ability "Ysgramor's Fury", this ability enhances the Nords' melee attacks.

The Altmer have the ability "Elemental Magic", the player can launch destruction magic attacks against the enemy.

I'm hoping they choose to add more weapon options, and I'm all for the option of an Unarmed skill line. Unarmed would be a great time for them to reintroduce throwing weapons back into the game as well, not just solely Unarmed! Perhaps a Mythic item as well as someone suggested earlier, just anything new to add to the weapon's section.

That being said, I can understand the mountain that is adding a new weapon type to the game, considering the sheer number of skins they would need to compensate for.

(But that's also more reason to add unarmed, because you wouldn't need to make any skins!)
