what's the point of a pet job? Either it brings balancing issues cause pets are too strong while it's master is in a save spot or they are at best comparable to any other DD (not used atm) and this way probably not getting used for content.
I wouldn't mind a beastmaster or summoner though, since both classes feel very FF-like. Just seeing issues with implementation. Especially with summoner and current direction of the usual summons like Ifrit and co. Or does everyone just wants to run around having an elemental spirit follow you..? well in this case summoner could be easily branched off of CNJ.
