Add a "can they see me" indicator?

But not always.. I have had several occasions where folks saw me but I didn't see them, or vice versa..
What would be nice is if (for the more sneaky folks out there) if there was a way to target a tank and know if he saw you back. It could be an additional skill that you can apply to one of your characters..
Its not Camouflage, but rather "Observation" (or some such) by which you can tell if you have been detected. You can put a little eyeball with a slash through it icon over a tank that doesn't see you or something..
Thoughts?
