If you have your epic you can also slowly root rot geonids in WL in your upper 50s. I don't have a lot of experience with it...but you could potentially go find a panther (or raptor?) outside the cave to throw at 'em too. Haste, DS, and just send it in as cannon fodder.
But yeah, I found Chardok to be a nice blend of XP and money. It was tough at 50, but by 52 it goes much smoother w/ charm duration and getting Call of Karana. Bind outside the entrance. You'll also get a lot of drive-by C2s from farming enchanters.
Keep an eye on /who all shaman and enchanter, they make
excellent partners as your charmed dogs will go much much further against slowed mobs. Malo or tash and backup heals or stuns mean you can use your pet haste spell AND not have to worry about breaking the charm pet before the target dies. In a duo (or any size group for that matter), pets will not steal 50% of the XP no matter how much damage they do.
Ideally you want your charmed dogs fighting sarnaks and NOT other dogs. This will greatly reduce the chance of you running out of charm pets.
Snare earring, DS gloves, DoT bracer, and velious BP regen clicks strongly recommend, if not essential. Epic also highly recommended of course.
If you get a really good handle on the mechanics and for the zone, you could possibly farm
Observer Aq'touz at 58/59...but you'll probably wind up doing what every other druid does and go bind in bear pits and just get to 60 on the best XP in the game.
OP, what level is your druid currently?
