Scouter Lens & Class Detect
Since the change in AW these Mastery have lost most if not all of their value. My suggestion is to turn the a class detect into a mastery detect.
For example, in AW I can see that my opponent is a Mystic champion but I would like the level of some of their Mastery is at. Do they have Mystic Dispersion? Is so at what level? What about Deep Wounds?
