He said in the video that the gems are the highest dps so you will want attack speed to help the gems go off more often and more defense to survive.

The reason I would think that he said not to is because you only use corpse lance when you are in land of the dead which has a long cd meaning its not very useful since you rarely cast it. Yes, that's because they all see that corpse lance is the highest damage skill of the build and its using cold rune. If you check leadersboards, overall you see people using Cold elemental stat.?

So what elemental stat are we using for this build? In the video Rhykker says none, and he says to explain why, but he doesn't eventually. However, less wind-up on damage due to not using Endless Walk might minimize the added damage necessary by just a bit. The upside is that it would allow for the extra passive and another skill on the bar, but unless those things result in a net damage 33% higher as spec'ed, you're just getting more flexibility, not more outright damage. On second thought, since other procs just increase the initial multiplier of Krysbyn's instead of getting a new multi altogether, it looks like that would equal 75% of the damage output of using Endless Walk.

Not to mention the fact that Blind Faith should keep quite a bit of damage off you during setup anyway since blinded enemies just stand there doing nothing. It might not be as useful depending on how long you can keep the status up and how much running around you do, but wouldn't you possibly get a significantly higher dmg output if you did something like take off Endless Walk, actually wear Wisdom of Kalan, equip a Hellfire with a passive of your choosing, throw RoRG in the cube, equip Blinding Faith with a ~40% blind proc, and then drop Decrepify from your bar to any other skill of your choosing? Trag'Oul's Corroded Fang should always put Decrepify on your enemy within a couple seconds at most for the damage reduction. 5% and Bone Spikes generates 2 - 5 additional Essence for each enemy hit. Every point of Maximum Essence increases your damage by 0.
