Would it be too difficult to add the enemy target UI graphic (yellow/orange box) to the Target's Target system? (For those not sure what I mean, if you target a friendly and then cast an attack power you will attack their target if they have one) It would be great if that enemy had a target box as well as the friendly box when targeting a friendly.
CoH was one of the first MMOs with Target's Target functionality, so I understand why it isn't in place, but the code objects to make the box are already in place and should just be triggerable for the UI to light up on the Target's Target's object ID. (Assumption I grant you, but this seems within easy reach without a deeper look into CoH's code base.)
