Druid just hit 24...how do I solo?

[wagorf]

Just hit lvl 24. Given my spell availability, what is the most efficient way to solo?

I've been doing the following: Thorn myself, pull with DoT, melee and dd until it's dead. Every kill seems to use up almost half my mana. This means I can kill 2 before I need to afk/med. Am I doing this wrong? Because this is crazy slow and boring.

Also I JUST realized druids can use fungi...at lvl 24 is it even worth putting on a fungi and something like girdle of rapidity to improve my melee?
