After playing for many hours with character contours on I deactivated them as I wanted the game to look a bit better.
Of course, friendly fire occurred more often, I got lost from the group more often, Hunger in the Dark and Blightreaper darkness felt like an enemy once again and game looked better overall without the outlines. As WHC is one of my go-to chars, the tagging mechanic came under a new light. Besides the extra damage, the contour struck me a solid help for all players, especially in the dark.
What I need to know is does the tagging become tiring to team mates? I do it almost compulsively now, even on other classes. Would it be better if the contour appeared only when vision is obstructed or make the tagged enemy stand out by other means?
