Shaco's invisibility

So one of the most frustrating things is dealing with a Shaco right now. His early ganks are so ridiculously effective. Riot took away Evelynn's level 1 stealth because they felt the early game cheese ganks weren't fair. Right now, Shaco is doing the exact same thing. Control wards don't spot him which means that it takes insane reaction time and usually a summoner spell or two to even survive a gank. Twitch can do the same thing, but at least twitch doesn't have hard CC.

It isn't like Shaco falls off either. Shaco is an incredibly strong split pusher late game, and his ability to waltz invisible through a team fight can allow him to be effective at all stages of the games. He can blink over walls and do insane amounts of damage, whether he builds AD or AP. I'm not saying he's broken, he's only sitting at a 52% win rate which isn't that bad. But some more counterplay then staring at the edges of your vision waiting for the minute puff of smoke particle effect to appear to let you know to start running would be nice.
