I did extensive testing with another clan mate last night with 86 wpf in throwing last night, Seems that the 14 penalty starts tiering higher with higher armor, Not just the EFFECTIVE armor penalty that hurts your wpn prof.
seems that the more armor you wear, the higher the penalty becomes, If he wore light armor he could pick up PT 5 weapons, but with just a slight ajustment in armor he no longer pick them up.
With plate armor seems that the 14xPT whatever forumal Tiers up close to 17-20 x PT.
Just thought u guys should know.
eventually with the PT penalty you can only pick up PT 2-3 weapons
