Re-reading this, maybe a summary should have been in order...
- AggroPC but can't See Invis = Scowls (will not agro you if invis is up)
- AggroPC and CAN See Invis = Scowls (will agro you if invis is up)
- Not AggroPC and can't See Invis = Indifferent (will not agro you if invis is up)
- Not AggroPC and CAN See Invis = Scowls (will agro you if invis is up)
- AggroPC, mob is on KingXorbb faction, you are ALLY with KingXorbb = Scowls and will attack you, cause he's just angry at everything (same invis / see invis rules as above)
It seems certain that same rules applied to conning while Rogue was Hide/Sneak, but I know there is some debate as to whether or not a true 'See Invis' mob could see a Rogue Hide/Sneak.
Sneak, as far as I can tell, still worked as Indifferent if behind the mob. I believe it was just a check to see if you were in the awareness radius as it was call by the dev team and ignored faction completely.
