conj guild lvl 25 quest

im having some serious problem with rhis quest. the cap is 29 and im 27.

i tried to focus fire on the earth elemental - the conj npc die and i get my ass kicked by the treants and elementals.

i tried to assist the conj npc in dispatchinf the mobs, they still die and i get my ass kicked by the treants and elementals.

do i try to get 2 more levels and aim to burn the earth elemental down before the treants overwhelm me?

I was able to complete the quest at lv 25 without any issues. I forget the order in which I killed stuff, but I am pretty sure I killed the blob things first, later in the fight the wind and lightning elementals come to assist you. Never once did I have to heal any of the NPC's.

As I right remember, I had some problems with lvl 30 quest, but lvl 25 quest was quite easy....
