Where to hunt in my 20's

[Aetherial]

I have inconsistent play time, on again, off again so I can't really group often.

Any ideas where a level 21 Enchanter should look to level up? ... I can still squeeze out another level from Oasis (ugh), although it is getting to be pretty crappy experience.

Ideally, some place where I can control the flow of Mobs, and that isn't more than a couple zones from a city.

I did Sol A in my 20's as a ranger, but I don't think that is going to work well as a solo chanter, at least not at 21.
