So, about ranjit... (slight spoilers)

[Hezzlocks]

I want a proper pet class, where I can fight alongside my pet, and at times fuse with it like Ranjit for boosted, powerful attacks and defense.

This WOULD be kinda fun. Sort of like RDM except instead of swapping in and out of melee, swap between being a melee-lite job commanding your pet to do stuff, and fusing with your pet to unlock incredibly powerful magically infused melee attacks.
