I'm not a big fan for the aggro icon. I can understand its purpose for newer players or people that just want to know what enemies aggro or not, but a lot of people (like myself, obviously) prefer the surprise and danger of not knowing what aggros and what doesn't. In addition, when you're in an area that has tons of aggressive enemies, it looks downright ugly to see dozens of red dots all over the place.

Please include an option to turn the aggro icon off, or at least make it more subtle.
