Similarly, I don't get why paladins and especially DK's can't use fist weapons. I don't get why rogues can't use one two handed weapon instead of two. Conan the Cimmerian was a thief in Zamora, he even scaled the Tower of the Elephant looking to steal its riches. He used a big old axe. (Of course, he was a barbarian, maybe he didn't know he couldn't. He wore plate armor on a few occasions as well.) If hunters can tame talbuks now, why can't they tame horses? For that matter, why can they tame animal friends to go into battle with them, but can't convince any of those friends to let them ride on their backs?
Is there anything you think you should be able to do that you can't?
