Agreed, all of this. Not to mention, Dark Discorporation will provide this same incorporeality as standing wraith/core incorporeality, making it further useless. And with the procing on 50%, in the heat of battle, it is far to easy to accidentally swing and turn it off. It just makes for a really bad T5. This should be lower tier thing, or make it stack and not broken on cast. Or combine it with an Ascendant Step type feature. That would make a great T5. I can't stress this enough, Dark Discorporation is a very lackluster T5 as it stands.
Very few modern trees have gaps in the enhancement map and Palemasters with this iteration still have two. Please consider a) making the SLAs a static 2 AP, 1 rank and filling the gaps between. Burst can be moved down to T4, with Harm added as the top of the line at T5 (or FoD or another Necrotic spell). Dark Discorporation, as it stands, can be added in T2 in that line. In Dark Discorporation's place in T5, either an SLA like FoD (The Necromancer Enhancement tree should really be getting this if Warlocks do, unless this is planned for Archmage,
plus an easy add as it already exists) or a +Neg Crit Chance/Dmg ability, either passive or a burst ability. AP wise, that makes 10AP for 5 SLAs instead of 9 for 3, and fills in the gaps in the map.
As for Animate Ally, I love the flavor, I do, but how about it applies the lesser form of your current shroud? Only one other raise option puts a debuff and that is reincarnated, which is normally ignorable. 20% attack speed loss is something no one wants, even with the 20% bump in damage. Mathematically, it will always be worse. I guarantee you, people will avoid using animate ally as it stands, especially since everyone uses UMD raise/resurrection.
Alternatively, you can change the numbers on Zombie a bit. A 10-15% speed loss with 20% damage buff is a net gain and is therefore far more tantalizing for both melee PMs as a form in comparison to Wraith or Vamp and as an animate. Or change the numbers on Animate Ally to be dirt cheap, low cooldown, a budget resurrection.
