As Kranel said, it's a limited job with a separate leveling system, so it will almost certainly start at level one and cap at level 90, with Blue Mage.

I'm looking forward to Beastmaster, too, and I hope they do it justice. I love scavenger hunts, so I'm looking forward to going around and hunting down monsters to capture.

Also, a whole-hearted "yes, I agree" to the plea to find a way to make previous areas alive again to encourage revisiting them (apart from the standard things like looking for maps or grinding relic weapons).
