i prefer 21/18 7ps 6ath 6wm and 4 if 
well me too... but they're talking about shielders  

. so 21/18 will have 4shields instead 4if. or 4ath 6shields (imo better for shielders).
also IF works best when wearing heavy armor. with light-medium armor, imo IF is not worth and those points could be converted for a 1 more powerstrike or WM. 
about the extreme attribute builds (i like them), this is not bad for a STR 2handed. strength compensate the lack of IF. 69hp give survivability if wearing heavy armor:
