meaning its entirely up to Z either to abandon this stance or stay with it...
weve (our group) told him about this flaw personally however i got it that he is comfortable with this fighting style (stance) that he's not willing to gamble and abandon this and in the process, to his mind, expose himself to greater risk (of getting hit)...
one of the major reasons why Z is hard to hit is precisely because of this stance... he ducks a little low then pivots either to his right or left (but mostly to his right) and voyla, he's already out of reach of his opponent... this is why Butchoy is so sleek and too frustrating an opponent. however, to maintain this "sleek-iness" he has to sacrifice the power department.
FR pointed this out early on... right from the very first time he saw Butchoy. FR told us previously when we met him personally - "Gorrez' punches are not soft, its just that he has some flaws in his stance that he cannot get enough leverage in his punches..." thats straight from FR's mouth.
