It looks like a new beta build is being prepared and it includes some interesting things for Demonololgy.
"While using Metamorphosis, your Hand of Gul'dan spell transforms into Chaos Wave."
Very nice indeed. It was really annoying having 2 of your spells just stop working in demon form. My only gripe is that it deals Chaos Damage, while Chaos Bolt is still ShadowChaos Wave
200 Demonic Fury 40 yd range
Hurls a fragment of chaos to strike the target and all enemies within 6 yards for 1869 Chaos damage.
Doom has also been changed. It seems instead of having glyph of doom to change your corruption, it now becomes Doom during metamorphosis.
"While using Metamorphosis, your Corruption spell transforms into Doom".
