I mean - this are limits on constant carrying...for me at least it would be much too high ( I guess I might have about a 5 if I add my T an Str ;D ) - I cant carry 27kg for a long time without any fatigue.
And an average Acolyte with sum 7 of T and Str could carry 45kg ?? To me that would be much...
I think putting the whole scale 1 step down each would be far more realistic.
ALso...why again are the Ag caps on armour gone again ?
