We're far out from 6.0 -indeed, 5.0 hasn't been released yet!- except, you know, they will probably start working on the major 6.0 content elements within two patches of time (for reference, Yoshida said one of the 5.0 races started work in 4.1).
I'd really like a healer with a non-feminine image, and a tactically interesting pet job with severe micromanagement. Beat Scholar and Paladin's 38+ buttons!
What I expect is that we'll get two DPS: one that uses scouting gear and one that uses maiming. The logic, like it or not, will be on par with how "ranged physical DPS" needed a third job.
