Yeah im not sure he's talking about the DoTs. I have several spells that hit fairly well and can be used combined with DoTs and shields. Specifically the winter line and the gust of wind. I am level 38. My rotation for damage is Swarm of Flies, Greater Frostbite, Gust of Wind, Winter's Fury, Gust of Wind, and I watch my shields. If you do this, let's say fighting giants in Scarwood, it works fairly well; however, you will be medding a lot.
Dot - hits for around 20-30 a tick
Shield - hits for 20 per hit
Frostbite - slows
Gust - hits for around 150-200
Winters Fury - hits for around 550-600
Sidenote - I think another plus for druids in a group is the group portal. I have saved my groups many time with this spell.
- these are quoted from memory and im a disabled vet with a brain injury so i might be a little off on the numbers.
