I main as priest. And Yes, Crudze is right, u should put all stat points to INT if u r support priest, WIS is useless. Generally as support priest u will rarely fight so u can be lazy and not add WIS to wear priest armor. As for battle priest, it is very important u have the proper armor so u might consider putting enough int just to equip the sets. That said, obviously it will be better if u focus on STR. If u r rich enough to get a full set of G equipment, then there will be no stat restrictions and u won't have to waste points on int. Using G Equip of course will be quite costly so it really depends on ur situation
