First off, the strength is slightly to low; Ideally you want a 80/60/80 build ; what this enables you to do is fight pures who are not actually built for staking but think they can stake. You then box them, they make the assumption they can win when truthfully they have no chance. 30 Strength though is way to low, 30 strength hits around 4's kicking at max. 60 strength hits 7.3's and 99 hits 11.3 (just as an indication) 60 strength is a nice option and often the more popular option because it isn't ranked in HS
