We should all keep in mind that these are merely the classes but have a full effect on our outcome when it comes in terms of what jobs will be attached to them. And thus I will vote for Caster. (Here's hoping Red Mage makes an appearance.)

If everyone has it to 50 how will it be hard to find? >.>

Honestly though how many healers does the game need? They'll just end up feeling pretty much the same anyway. They should add more unique classes instead of clones of existing ones.

lol I meant for exping.

That's a pretty common misconception.
I guess that, like the majority of us, the only other MMORPG you've ever played is FFXI, right?
Because your post describes exactely the situation in FFXI.

Other games successfully managed (and we're not talking about just a couple) to create classes with the same role that play completely different from each other.
For example the healer role, I could simplify talking about a standard healer that cures through normal spells (very simple and straightforward), one that heals through damage mitigation (doesn't have a lot of healing spells, but has a lot of different "shields" he can apply to several targets at the same time) and one that heals through time (having several different HoTs in his arsenal).
There are many other versions as well, I could make you a more practical and real examples taken from released games if you want, but I'm sure you'll just trust my words.

The point is that it's absolutely possible to create classes with the same role that play and feel completely different but have similar efficiency in their main purpose/role.
It all comes down to the game designers being good enough with ideas and originality

For Scouting Class, I would like to see Thief (Class) -> Ninja (Job)
For Mage, I would like to see Arcanist -> Time Mage (somewhat of a stretch from the initial concept of Arcanist being a 'trap' based mage, but no more of a stretch than Arc -> Bard)
For pet... not so sure, perhaps Beastmaster/Trainer -> Summoner?

Personally, I would prefer to level Thief, but the class/job I believe the game needs is Time Mage. As long as arcanist gets basic damage/cure spells so it can solo Time Mage's Regenga, Slowga, Hastega would make them a great buffer/debuffer for party play.

Since I hate magic and like to do things by my powers, I prefer a Scout class =)
