The most efficient way to kill Paineel guards on my shaman.

[Tobius]

Just tested it, nuking leaves me with 67% mana while dots and debuffs leaves me about 58%.

When do dots become usefull? Longer fights where you can't nuke them down to 0% but the dots will do more overall? How do I gauge this?

I'm going to test meeling the greens with no spells.
