Does it make sense to get good with a two-handed axe, but then have no skill with a one-handed axe!?
Actually that makes perfect sense. A battle axe is nothing like one-handed axe. A battle axe is far to heavy to be used the way as a smaller axe. My argument is, weight is the key difference between weapon proficiency. Training your joints to slash, thrust, and chop with a one-handed weapon would allow you to use any weapon of similar weight and grip to the same effect. Any true combatant would instantly recognize their weapon's strength and weaknesses and adjust his tactics accordingly. Now if that same fighter tried to use a heavy weapon, which requires two hands, he would run into difficulties. The weight of his swing, the balance of his form, and the strength requirement in general would require a new set of skills. He would have to train his muscles in both arms to move accordingly. A person could easily hurt them self using a heavy weapon without proper conditioning.
Now people like to throw up the dagger card, which is silly. Ofcourse using a small weapon is different from a sword or axe, but considering the dagger is the only "small-arms" in the game, we can make an exception.
I can understand how people like multiple skills, but saying this new system isn't realistic is non-sense. I've never cared about the skills, it never affected how I played the game, but I feel the skill list seems more organic and real.
