Please help me out, not a "How's my spec"Follow

My Girlfriend and I both happen to play Wow, same server, same side, same guild, same class, and even same race. Obviously, since we both started off pretty close, it's kinda a race to see who's better, and such. So I looked at our Armory profiles today since she's about to overtake me leveling, and lo and behold, she's better than me at... well.... everything.

Obviously, my guy COMPETITION!!!! infused brain will not take this sort of punishment.

To just highlight a few of the problems I see (keep in mind we are both the same level, and pretty much only wear quests items, with a few exceptions):

She has:
Around 80 more agility than me
400 more Health than me
30 more stamina
200 more attack power
The minimum amount of damage that she can do is the same as the maximum amount of damage that I can do.
Heck, even her crit chance is higher than mine, and that's what I work owards the most.

I should point out that She is Sub specced, and I am mutilate specced, and this is the only thing I see different about us.

I'm just wondering if there's something about our specs that just makes me look bad on paper, or if I really need to rethink something. My Armory link is posted nelow, and if someone is really looking to help and needs some more info, I'll post hers as well. I just really can't understand how I would be this much lower in everything without running around naked with the starting daggers. Anyhow, help would be much appreciated.

It doesn't mean that you'll do bad damage than her, Mutilate build is all about crit, you can have lower AP but your crit rate must be high. Imagine she got the AGI buff from her talent, where you don't. You get the crit CP where she don't.

Learn the talents and play it well. ;)
