I agree with a downgrade in AGI and ACC, maybe not that harsh as you suggested, I'd put him on 75 AGI and 78 ACC. Also raising DA and SP sounds good to me.
About my own suggestions, maybe TS could go a point up, over long distances he's neatly fast. I'd also like to increase Balance by 1 point and Stamina to 85. I see him more resilient and enduring than current numbers make him.
