Personally, I would love to see a couple of things.
Rune Knight - Hybrid Magic/Melee job, where spells are "weapon infusions" and abilities designed for melee combat, with an added ability to absorb elemental damage to boost their own damage output OR build elemental tokens to unleash powerful abilities in melee.
Spirit Warden - Ranged Magic job, with spells revolving around seals, absorbing spiritual power from fallen foes and draining more powerful enemies to fuel more powerful abilities.
Chemist - Ranged Physical job, adept at throwing flasks of explosive, corrosive, flammable and aetherochemical devastation. Auto-attack throws daggers. Weapon and off-hand are single dagger and flask. Gauges include building up compounds (tokens) to unleash powerful flasks upon your foes, and a mixing gauge that builds up as you go through combos. At 25%, allows the throwing or consumption of healing flasks (limited filler healing). At 50%, allows throwing or consumption of buffing chemical concoctions. At 75%, allows the throwing of powerful elemental concoctions. A final gauge, in the form of small tokens (up to 3), fills with the completion of a combo (utilizing the ender). Every token adjusting the "ultimate bomb" to throw. 1 token makes it a stunning single target explosive, a 2nd token makes it an AoE flammable mixture that causes a time-limited DoT in the area it was tossed, and a 3rd token making it a powerful bomb (could be elemental or otherwise).
Will we get these or anything similar? *shrug*
Just thought I'd share the ideas.
