So there's a lot of changes in pre-patch and many more incoming.
What I would personally like to see is stuff like this (name yours btw):
1-Army of the Dead 10m -> 5m CD, Duration 40s-> 20s
2-Apocalypse 90s CD -> 60s CD to better align with Blighted Runeblade and cool factor. Could take a bit of dmg somewhere else to make up for it
3-Dark Transformation off-GCD, this one is so obvious and the biggest of them all for me personally.
4-Fixed WW so it doesn't bug on everything and so roots and other movement-impairing effects don't affect us
5-Soul Reaper changed to instead burst up to 3 Festering Wounds and giving 7% haste for each.
6-Defile actually buffed to be competitive to DA and SR
7-Pet HP increased...
8-...Huddle/Protective Bile reducing dmg from Corpse Shield
9-Reduced GCD, 1,5s feels so bad and slow
10-Double Doom in Artifact actually increase our all DC related effects by x2
instead of 2 charges so 2x dmg, 2x CD reduction on DT(with shadow infusion), double chance for Scourge of Worlds. Would actually make DC feel powerful and you'd want that proc! instead of DC x12312 for no dmg.
Some other potential cool stuff:
11-what if Virulent Plague Eruption also added Festering Wound to the main target (one affected by VP, I know, might be op, just a thought:P)
12-Clawing Shadows, would want to simply see it as melee full-shadow SS instead of ranged. Didn't pick melee to spam shit from afar
Yes, some of it may be op or sound op, you may disagree with a lot of it and that's perfectly fine. Just something I would like to see and would love to hear what others have to say/add.
