for the most part I just burn things down but there are of course times you will run out of mana and rather then standing around like a knob I do have a couple buttons for melee type stuff.

for 1-2 packs of mobs I dont often use many offensive totems due to their mana cost and short life span of the target. If its one big meany ill use stoneclaws and fire totems. If its large groups of trash then stoneclaws+magma/nova totems. If I know I will be in a spot for several pulls I drop a full spread of healing stream, mana spring, grounding/tremor/earthbind/stoneskin regular flame totems since they do better dot for the mana cost. etc. The totems I use the most now is a combo of 4healing sprind and 1 mana spring since the mana spring one doesnt stack (mana tide does though).

my spec is full elemental (got elemental fury a few levels ago and it made a huge difference) next one will be elemental mastery woot!
