Druid Soloing 44+

[Estu]

I've slowly been leveling my druid solo over the past few months (slowly because of not a lot of playtime being invested) and he is nearing level 44. For quite a while now he's been in Firiona Vie, quad-kiting first pirates, then drolvarg growlers, and now drolvarg snarlers with a high degree of success. I recommend this zone to any druid 34-43 looking to do some quad kiting: just leave the city of FV by the bridge, take a right, follow the cliff, and you'll get to a nice area with a lot of roaming monsters you can pull from and a nice monster-free area at the cliff you can kite safely in.

Now that the druid's nearly 44, though, quadding snarlers in FV is soon going to be no longer an option. They'll stay blue for a few more levels, but not much longer than that. So I'm looking for good options for the rest of this druid's career solo, 44-60 (or maybe more like 47-60).

I'm willing to consider quadding, charming, and root-dotting. I don't want to kill good guys (e.g. Butcherblock dwarves). Zones/camps where there is not a lot of competition for spawns is preferred. Where have you guys had success?
