Yeah, Omnicron, take those stats out.
Anyways, i am still a noob and have not played many games with tau, and am 12 also. I have found them fairly easy to play with. You just need to set up your army far away and blast the hek out of your enemy, and if they start to get close, move your FW in a devilfish. You need to be mobile, and stay out of CC, and you will win most of the time.
Don't forget to have half a brain.
There are some armys I find hard to beat, like Necrons, but that may just be because the people who play them in my area are good commanders.
