I think confuse will be added in this expansion. They've had a song programed for awhile that gave resist against it. amia seem to be necromancer esque by their description. Also think they'll be able to charm or confuse based on being "bewitching". Imps will probly agro just to be bastards, and also have a horn which could confuse or stun and probly act as a long range linking thinger. Apkallu just look like this expansion's eft. Little native things that don't agro but can/will beat the shit out of you if needed, while using annoying abilities. The fat fishy thing is most likely just a new pugish thing, maybe even able to eat people o_O? Wild guess, but eh. Wonder what the food effects will be from that aybe def+ from the fish being high in defense? Says scales for defense, but I don't see any scales on it lol.
As for jobs, I think gambler, juggler, and alchemist could work alongside blue mage. Gambler, melee with random based ws/ja :D I'd love to play as one

Juggler could be like a ranger with throwing I guess, maybe even some throwing ws finally. Would be nice if SE made some cheap to make or npcable throwing things for them, or have DD chakram and stuff. They could get the juggler abilities that confuse and crap, or add those to ws. Smile could reset a random ability (not two hour) to a selected member maybe o.0 Alchemist~ kinda like a more melee and healer based rdm. They could use things that are kinda like ninja tools to mix that alcemists could make so the real alchemists don't get pissed off about them stealing their job.
Light enfeebles, maybe some self buffs, and of course ^^ cures! Think it'd work out very nice, especially with a nicely working dd side to it as well (not talking rdm dd).
<.< Oh, and I think that dude in crimson is a drk, his scythe is just at the end of a swing and facing away from the camera.
edit: Took out the accidental Miyamoto thing
