So, about invisibility...

I think there should be a trinket that reveals enemies who are invisible. There is literally NO way to see someone who is invisible, which makes for easy assassination. Take Shaco, who I was recently in a game with. He would come out of nowhere, and I would suddenly just see my health plummet. (I was the jungler, and I'm not a very good one at that.) I think there should be at least SOME way to see invisible players, either by item or trinket.

If there is one, call me a noob and tell me what it is, please.
