So I got some hero question......

1)Are hero smart enough to sneak in a stance while activating a attack skill?
2)Need a good pve interputing built for Norgu.
3)Is it possible for goren to be a little smarter?

1) Not sure what you mean, but if you mean use a stance while using attack skills, then yes. Simply, because the Ai seems to use stances as often as they recharge.

2) Purely offensive interrupting build::
Max Domination, 8-10 points Inspiration, rest in Fast Casting

[skill]Cry Of Frustration[/skill][skill]Power Drain[/skill][skill]Leech Signet[/skill] -or- [skill]Web of Disruption[/skill][skill]Mistrust[/skill][skill]Empathy[/skill][skill]Backfire[/skill][skill]Mantra of Recovery[/skill] -or- [skill]Psychic Distraction[/skill][skill]Resurrection Signet[/skill] -or- [skill]Signet of Disruption[/skill]

Or just use::

3) Goren is as smart as any other Ai. He is no "smarter" or "less smart" then other hero Ai. I am sure they are programmed at just about the same efficiency level as eachother. Give him the same setup you have for your Koss, he will act the same...

Hope all that answered your Q's.
cheers!
