RIOT PLEASE HELP ZED.

I wonder when riot will buff or rework zed I being playing league since season 2 I main zed season 5 . But since then zed is now one of the most weaker assassins in the entire game . His ultimate is easy to counter his w cooldown is so long . His base AD is weak. And there is a lot of people who wonder when zed will come back like the main mid AD assassin. Pro players like Faker , Dopa , LLstylish. And more has the same question. And you should buff nocturne range ultimate. Too. I mean now the meta are champs , some people dont like . So I ask my self what is the purpose of to many champs . If the champs some players like most are always weak . Or we do need to play only the champs riot want us to play?
