....as well as mind manipulation...
That's more about Azure's way feature afaik... At least that kind of more direct mind influence.
Dark way's mind influence could possibly (and imho) mean some fear invoking, or something like that.
And... to my opinions.
Dark way is, or shouldn't be evil. Always depends on use of the way, crystal or azure can be same evil as this one. Just the source of energy and potential of spells is different then other ways. It has closer to being used for wrong things though, cause it's essence.
I would like PS to restrict from the common types of gameplay we see everywhere.
Dark, brown, red way = Evil characters (ala horde in WoW)
Crystal, Azure, Blue = Good characters (ala Alliance)

-Next point is.. Yeah, I'd like to see possibility to train dark way without dieing. Most of reasons are said in this topic already.
-Next point: DR should be something what player, same as character really, really regret to enter. (I really hate that characters who run out of DR in 2 minutes, stands next to you and mumbles 'Meh, I really hate that'.. feels weird.)

Just my opinions.
