I always wanted to do a crack lance and since I dont know if mathil will finish his one, I took his build and did it the way id probably build it. I would love to build it with a natural affinity because it would fit perfectly but sadly its too many points (I usually play my builds up to lvl 92-94). Also im done with the league *sadge* but if it stays the same in 3.17 I probably try it as a second or third toon.
