If it's a pet job it would probably be a copy of SMN which....sucks at being a pet class ^^"

Maybe a FF10-2 berseker type then ?

Some kind of a monk but with the berserker attitude of the WAR ? Could be fun to have some abilities that makes your character attack frenzy with loosing the abilitie to control it for some times (would require a good knowledge of the fights which could bring some challenge)
And we could have a LB that turns us into a fuzzy monster (would love to see this applied to Lala xD)
