I want Warlord to stay at +2 AP per kill, but Rage needs a pretty big nerf. At the very least, Rage should prevent you from using any skills for the duration of the effect - normal attacks only. That's probably still not enough.
Hail Strike is far too powerful for a 1 AP spell.
I kinda agree with Necromancy. I looked at those and didn't see too much which was worthwhile. The healing through blood one was interesting, but not worth the skill slot which could be filled with the more-useful Restoration. There just were not all that many exciting skills.
Shackles of Pain would be more useful if it worked like Netherswap and allowed you to link two targets. That would allow you to tether two enemies together, or allow your mage to tether the warrior/rogue and an enemy instead of herself and an enemy.
Walk in Shadows is garbage-tier. It was unimpressive given all its flaws in D:OS EE, and nerfing it to need 3 Memory and a Source Point makes it completely worthless.
Teleport is very useful for out of combat stuff, so if it needs a nerf, increasing the AP cost to 4 would work.
