Blind was fixed in a previous patch. Enemy doesn't know what to do. It is true that this is not ideal or the design we desired but it's hard to change it without messing up existing savegames.

Taunt was never broken afaik. When you are taunting, you have a much higher chance of being attacked. We don't really have an aggro system the way you'd expect us to, so it's the chance of being attacked that is higher, this doesn't necessarily mean _everyone_ will attack you. Also, smarter enemies are harder to taunt.

So if you have more info, please tell us smile
