[Quel'Danas Isle] Emissary of Hate has a strange spawn and pathfinding.

[Rorschach91]

Current Behaviour

Emissary of Hate seems to spawn only when a player go near to the portal.
If it is not in combat it patrol the area near its spawn point.

Expected Blizzlike Behaviour

I cannot be 100% sure, but as I saw on Cata PTR and TWW PTR, Emissary of Hate seems to spawn near the portal, and patrol the way.
Evidence: Youtube

Source

Cata Classic PTR and TWW PTR

Steps to reproduce the problem

1. Go to Quel'Danas
2. Go near the portal (The Dawning Square).

Extra Notes

I don't know what manages its spawn point. This npc doesn't have a spawn point or a pathfinding in its database.
Could it be an event script?

Probably this issue needs a sniff.
