Only until you get your combos skill, 215 currently most of it solo. After you get Magic Missile is gg for most 170 and under. After you Frost cloud, nothing in the ground stay alive more than 10 second. Now if they fly, you very dead son XD.
Also i dont find warlock appealing, maybe im a super noob, but i will go W3-E3-Feather and enjoy my ST dps, as with the E3 i dont feel the need for more aoe. As for trying to kill everything by ranging, i have no problem going in putting the bleed and going out. and surespell+Quickcast+drain on paper looks like a butt load of dmg in a few seconds.
Then again im a noob and probably f myself by not going warlock, then again ill be happily f. Since i really like the concept of Feather and Elementalist together.
