[NPC Mechanic] Casting while crowd-controled.

[Ashamedlol]

There are NPCs that still cast while either fleeing, stunned, feared or silenced which doesn't seem correct (for example Azjol'nerub's third watcher, he casts a 4second stun on you even when he's feared or stunned or silenced, OR Anub'arak in Azjol'Nerub continues casting Pound even when he's stunned (many many more who interact like this))

However there's also a simple bug about Anub'arak, when you stun him before he goes back to ground, his model still follows you which causes confusion.
