Mages, all 12 of you. dd staff + ds = full exp?

It's really just easier to reclaim and re-summon pet. Ride the 44 and 49 fire pets for as long as you can, taking advantage of their DS. By far the most efficient method for leveling. Don't waste mana buffing or healing them, just send them in and spam Burnt Wood Staff. As you get higher level, you don't reclaim just to avoid the XP penality, you reclaim because it's much more mana efficient than spamming pet heals.

If you want to keep the pet just group or duo. The staff really shines best in duo/trio situations, in my experience. 25 DPS mana free is no joke, and that's on top of your hasted pet and traditional nukes. A Mage/Necro duo fear kiting with Mage also spamming staff can run through an absurd number of mobs in DL/BW from 40-low 50s. Mage/Shaman and Mage/Cleric both also go noticeably faster with Mage who can spam staff.
