Game Mechanics: Mobs stunning instead of fearing?

[Rais]

Last Cazic kill (before today), I was feared by a toad. It made me run, not stunned me.

Every fear that landed up till today, feared me and I haven't been able to see if that was the case for todays dragons/god rush.

I haven't seen that issue happen on beta the few times I've been able to play there.

I think only the crusaders fear in Cazic. I noticed Ire Ghasts not(or rarely) fearing in Hate anymore, I just figured it wasn't their main spell to cast anymore . Maybe SK NPC issue?
