I think that another significant problem they'll be facing is the way skill/abilities work now. Mage jobs that only have 15 abilities/spells are kind of lacking. A pet job(summoner maybe) that only has 15 abilities would probably have 0 for themselves, or only have 1~3 avatars to summon, or an avatar for all 8 elements, an attack, heel, stay. and 4 left for other abilities.
Yeah we're probably gonna be waiting til 2.0
