What if the new Job is Beastmaster?

So kind of like Druid from WoW.

Nah, Druid from WoW is pretty standardized. You DPS as a Cat and Tank as a bear. The idea here is you could tank as any kind of Beast, since your weapon (Talisman) would result in the form you take. So maybe at level 1 you have a shrew talisman or something. Level 25 a Coerl Talisman. Using glamours you could then select whatever form you like at whichever level. So if you want to Tank as a tiger, but your current Talisman turns you into something like a Chimera, you can glamour the Tiger Talisman over the Chimera Talisman.
