A more efficient way to solo as a lvl 30 Druid?

[mmiles8]

So your saying for now just use Stinging Swarm, Creeping Crud and Flame Lick? And ignore Immolate / Root?

For pure efficiency, Flame Lick and your current highest Swarm dot is going to be the way to go. I'd never advocate blanket ignoring of spells. I do use root at times (custom picked to suit my needs, Grasping Cheapest, Ensnaring Balanced, Enveloping Fastest, Engulfing Longest) and I do use Immolate at times.

However, if you find yourself at low mana, or generally wanting to maximize your effectiveness for your play time, root is a waste when you can put forth the effort to take an active role in your mana regen. If the mob is resistant, use swarm line exclusively, they receive a -100 MR check.
