Predictions for job(s) in the next expansion?

[Morningstar1337]

Posts like this make me think people are convinced we are going to have 4 tanks, 10 melee, 3 caster, 3 ranged physical and 4 healers just to round out melee sets.

Well its not my fault SE opted to have SAM use Striking gear instead of its own unique gearset. The precedent is set, like it or not. (though I'm kinda expecting two for Melee gear-types rather than 4)
