55+ Druid leveling spots?

[BarackObooma]

You can quad in DL outside KC until 60.
54: pull dark blue drolvarg ragers (lvl 40-1), petrifier cockatrices (lvl 40-1), mountain giant steeps (lvl 40) and brutes (lvl 40)
55: pull dark blue ragers and petrifiers (lvl 41)
56-60: You now either have to start quadding Ravishings which have double the hitpoints (but go up to lvl 44 or dark blue to 58 or 59) or grabbing four greens (light blues). Pulling 4 "light blues" would be the same experience as 2 dark blues. It might be worthwhile to get in two green quads done in about the same time as quadding one set of Ravashings. Especially if you can't find four dark blue ones which most times you won't.

OR, since you're a Druid, if you want to be as efficient as possible, there's another route. Powerlevel people's twinks for 2k an hour. Take that 2k and pay for a Chardok proxy pull. You will get several hours experience for the one hour you spent. Repeat until 60.
