Well having most points added on STR and CON (1 STR and 2 CON)
is good thinking

but u forgot an important thing...Wind fighters r Defenseless (even after having Full Assistent Skills) against Spell damaging Skills
and sometimes u cant depend on teammates to buff u with Water Sheild or Stone Wall..thats when Vanish comes handy...but some ppl cant afford Goddess Skills (as i mentioned be4) so this my theory for those who dont have vanish

but its just a theory, Everyone has the right to Add points based upon their judgement, dont u think? :D
