How viable is... Druid Charmz?

[Natewest1987]

They have a) snare and b) sow... no mana regen at this era. Anyone have thoughts on this? Obviously it's only going to work in certain zones, but I'd love to hear anyone else's experiences with it. I'm considering giving it a go. My charm experience is solely based on necromancer & enchanter, where both SoW & Snare are horribly lacking, but exponentially advantageous. Conversely, my druid experience only extends to using it as a port bot after pling. Would the lack of mana regen hurt the druid too much? Would I basically have to have a mana stone to make this work?
