Good solo root/rot spots 30-40?

[Austrianna]

I'm leveling up a druid and have hit level 30 and am not sure where to go next. I've been kind of wandering around not sure where the best spot to xp is at this level. My gear isn't the greatest, so my mana pool is small. I tend to run into trouble if I try to quad or charm. Resists and charm wearing sucks away my mana and then I'm left trying to run away from a mob, if it hasn't killed me first ;p I'd much rather go the old root/rot method, at least until I can afford better gear and by proxy end up with more mana.

Any advice is much appreciated! On my cleric I grouped those levels so was in MM etc. I'd like to do something where I don't have to worry about trains all the time as well.
