Killer's blade is cheap, stamina based and scales to 300 percent. It's a great ability. My problem with it is that it deals magic damage. Between CP and my mace, I'm not sure how viable it is since the ability is neglecting my physical damage and armor pen bonuses. For you PC guys that actually have numbers to test these things, is killer's blade still worth despite ignoring armor pen and physical damage.
If numbers are needed for better calculations I can provide them.

Battle leveling for pve content defeats the idea of progression. Remove CP
