This is the log on there so you dont have to go back and look at it.

Your blade barrier === OBLITERATES === Nycoe!
The whirling blades around you disappear.
A sudden pain erupts through your skull.

I think the healer should not see who blackjacked him. I dont see Nycoe stepping out in that log. It should show like this, i think:

Your blade barrier === OBLITERATES === someone!
The whirling blades around you disappear.
A sudden pain erupts through your skull.

Its like youre a person who doesnt have detect invis and a necro fails sleep on you. Your initial counter attacks are against someone, until hes no longer invisible.

To me its just common sense.
