Yeah, CB will carry you a long while. Especially if you find a group for fast Centi kills to spread the belts around.
I don't have the information on hand, but someone did mention (or I read a guide) a week or so ago about how the Bone Chip quest turn in for Kaladim was proportionally good XP as Belts are for the level. And there are so many more skellies wandering BBM than GFay (from what I noticed while trying to do the HIE CLR low level spell class).
If you get a chance, look into your Initiate of (Brell? Not sure if you are Dwarf) necklace. It's bound to be easier than HIE.

Apparently lvl 12 recommended level, but WIS and Mana, not bad.
