I'd love the next jobs to focus on hybridity and support.

Red Mage: Taking elements from Mystic Knight, Rune Fencer, Fencer
Puppetmaster: Taking elements from Mime as well (and like Anarchy Online's Agent profession, able to imitate other jobs but in a very very very lesser standard. but giving more utility)
Dancer: Dancer is naturally a Hybrid anyway and has changed in each rendition, I would love a Melee based healing dancer, with physical aoes.

A healer that places buffs on others that have a certain charge that heal on getting damage, paired with strong cooldown heals against big hits.

For example ability 1: Places a buff on the target that heals for xx potency every time they take damage, up to x times at a maximum of 1 time every (1-2.5) seconds.

It would compelent both SCH and WHM and dont interfere with them, it would be a third type of heal that plays nice with both WHM regen and SCH shields.

Probably 4.0 for new job(s), but so far they've added:

2.0 SCH [healer] / SMN [c-rdps]
2.x - NIN [mdps]
3.0 MCH [p-rdps] DRK [tank] AST [healer]

So now

3 tanks DRK PLD WAR
3 mdps MNK NIN DRG
2 c-rdps BLM SMN
2 p-rdps MCH BRD
3 healers SCH WHM AST

The caster archetype hasn't had a new job added to it for a long time. Maybe another caster.

I think the possibility of samurai as a 3.3+ job is still there, beyond that we'll have to see where they go with the next expack. I believe that we'll be going to garlamond and ala mhigo. That puts a gunblade class on the table at that point. I would also like to see red mage sooner rather than later, but that could put samurai in the next expack and have the rdm in 3.3+ tied to sharlayan lore.

I'd like it if DNC actually danced during combat. My own variety of they'll-never-do-this would work like so:

Two(or more) dances, think stances. One focused on damage and one on debuffing at the least.
Several steps, think Summon I / Summon II / Summon III in that once you get a step by leveling or quest you have that level of step available during any dance. These steps would be something like Attack Step, Lame Step, etc.
Using the same type of step in succession chain-boosts their effect/power, but there could also be special combos too. Getting stunned/paralyzed/similar would immediately break the chain or combo.

Now, the idea is that you don't use weapon skill abilities, just steps(though there could be some all-dances WS steps too). What happens is you can queue up to X number of steps, and on each GCD tick you automatically execute the next step during the dance. This would let the dancing animation flow without sudden jerks as you fired off an ability, and be an interesting variant on GCDing(bonus points if your skill speed directly affects your dance animation speed). Later on you could get an ability to cancel your most recently queued step, but add a chance of Stumbling(reduced step effect/power for X seconds?) the more you try to backpedal. Depending on your dance, it would affect the step/move performed; say during attack dancing, attack step produces Blade Dance which does high damage, but during debuff dancing it's Kidney Stab with less damage but a small slow effect. As for a weapon, I'm thinking thin fabric sashes, connected to a pair of hand-held ring blades.

Magic based tank using 1H weapons and shields, with defensive cooldowns that sacrifice MP to mitigate damage rather than HP. Use of DoT attacks with emnity gains to manage emnity.

Beast master with attacks and offensive coolfowns that thematically use predators, along with actual summoning of specific beasts to handle attacks, similar to machinists turrets etc.

I dont know where i read it but Samurai wont be tank, they said they want it to be a DPS, but i doubt it would be a TP master like in FFXI.
