new KMST gear has percentage based ACC and AVOID

I don't think you did your math right. What's the total amount of ACCURACY on your equipments?

66 dex from base and equips
25 luk from base and equips

169 accuracy from equips/blessing/buff/mastery -- this is corrected after adding it up again --added an extra 10 from somewhere, after taking it out it only makes it worse..

Edit: Well definitely doing it wrong, I forgot that it's a bonus and not strictly a multiplier, 172 acc wouldn't be that horrible, still a massive reduction though.
