It looks awesome, but the main problem has not been addressed as far as I can say:
Pvp-opness.
Look at the Akegata, Shire. Uruz. Shishi. They are massive (especially the first 3) or at least large, bulky, high, wide. It is IMPOSSIBLE to dodge fire in them.
Your OC AT will just have to strafe to avoid fire while staying at max range and hammering targets with cruiser-like dps.
I love the model, it looks awesome.
BUT: Without major balancing thought, this one cannot be put next to all other BT without creating MAJOR in-class-imbalance.
