Greyed enemy icons
That are always on screen, and become colored when the enemy is in your team's vision.
It'll function just like the allied icons. So many times I've been screwed over by not being able to target my target due to them hiding behind their turret, being too close to a champ with a much larger hitbox like Alistar or just misclicking a minion on a champion like Fizz since he can waltz right through them.
Think about how useful allied icons make Shen... all champs should be able to utilize that feature, especially champions like Nocturne, Cait and Nautilus.
