The Defiler ability Soul Ward is broken. I cast the spell, it drains my life to 10% but it does not apply a ward. The ward icon in my maintained window indicates no ward value. I checked on ACT and no amount of damage was being warded from the ability. This ability became broken sometime during KA and has remained broken coming into PoP.
Was working fine as of two days ago. *shrug* Granted, it doesn't scale well at all with this expac (the ward applied isn't large enough)...but for an instant cast emergency type thing, it works well enough.
