Sometimes I think my eyes play tricks on me. With the Target Finder I think the center cross still turns red on Cold Blooded users, they just don't have the red diamonds around them when targeted. Don't now if anyone else has noticed this and can confirm?
gotta admit the target finders are very OP. not complaining though because I use it on two of my classes too. I was getting fed up of other people killing me with it so I decided to join the crowd. Don't blame me for killing you with it, blame treyarch for putting it in the game.
