Corruption of the RuneBlade replaces Unholy Aura?

[Map Designer]

Hello,

Corruption of the RuneBlade: creates blight on small/medium/large area. CoolDown improves each level, say: 10/7/5 seconds.

I always felt something wrong with the unholy aura.

1. It kinda felt like a sort of blight aura. but undead never gain move speed on blight. Why would they gain MS% from blight aura?
2. I am against Aura MS% bonus as a concept. it screws the balance between heroes. units MS should be balanced as they aura

Problems: it might fit lich theme more than death knight... tbh even Necromancer with raise dead should do that xD
not only that, but also there doesnt seem to be any lich ability that fits the death knight.


anyway, not sure how TC endurance aura should be reworked though? or if it should be left as it is.
