So far I like the 8T. Must be the build. Edit: I stripped the armour before posting. It has 448/494 armour.
you should probably add armor to your mech koma. Unless you have discovered god-mode, then don't bother.
I should have added this earlier: I've started stripping the armour off my mech before sharing it here. I found that my 9M kept getting torn apart very quickly after I posted it here. The 8T has 448/494 armour.
