its not so much there are newbs trying sub jobs its more that experienced players wanna try something new and narrow minded ppl cant see the uses so these unnusual jobs will never get a proper party field test the blm/nin is a very powerful spell caster makeing the enemy weak against its spells then casting the spell also with 2 int ennhanceing clubs the spells get quite powerful on there own sadly no party leader ever relizes its quality over quantity and will alwase pick a blm/whm or a blm/smn because they have more mp i myself welcome unnusual jobs i often invite odd jobs to partys to see how they do since i ussualy party with friends or ls members iv seen so many of these combos suck but i also see experienced players do extreamly well with these jobs while soloing
