Lol I hate u guys.
I read over some other forums and it seems now that requirements now are based off a combination of WPF and Power Throw/Draw.
I'm going to theorize that the formula goes along line lines of (WPF - armor penalty)/(100)*Power Throw/Draw = actual power throw/draw.
So if you have power throw of 10 with 54 wpf and 17 armor like me it would be 3.7 actual power throw which is why it gives me proficiency errors for all my throwing weapons and I can't pick up throwing lances or anything above heavy throwing axes. Now it still gives me proficiency errors when I use rocks so I could be wrong.
