Game Mechanics: Ogre Frontal Spell Interrupts

[Estu]

I've been playing my ogre shaman for about a week, and until today, he couldn't get knocked back or spell interrupted by melee attacks from the front. Since the server restart today, though, he is getting knocked back and spell interrupted. He still isn't stunned by bashes from the front, though. I don't know what the intended behavior is or what classic had in this regard, but I figured I'd note the change here since there's no patch note regarding it (and since Uthgaard told me to).
