Heh, I sort of meant that. I just worded it extrodinarily poorly.
AC is not very important at high levels, I agree. What I meant is that tank armor + elite, or a battle suit should give enough ac to MAKE it useful. It shouldn't be a matter of MK shield, reflect bracers, and reasonably good dodges... it should boil down to those also, but the formula should rely a lot on AC too...
I'd like to see AC more around 10000 at higher levels honestly... cutting 1k off each hit might actually be useful. Maybe even larger.
