That's odd, because I watched Dyrus and Sneaky play Kled last night in what appeared to be a ranked scenario. I mean maybe they had some practice on PBE before release? And maybe they were on their diamond smurfs or something? I forget. Maybe it wasn't ranked. Bad example. My bad.
Well I wouldn't call it stupid to play the game how you want to play the game. If that means first timing stuff in ranked then more power to you. You'd probably perform better than me for all I know.
I understand how hearing "first time" can cause worry, chest feels heavy, ya know. I get that. It happens. I just try to worry about me and keep my mind on winning the game no matter what happens... Except maybe DCs. Those are painful. I'd rather have a first time Kled than fight 4v5.
Edit: Look at this guy from NA, C9 I Shadow I, he's Master. That's pretty high rank..... He's been playing Kled since yesterday. First game: 10/2/7. Maybe they practiced on PBE? What is he, 5 wins out of 5? Playing at Master level? I mean yeah maybe he tried some normals or custom games first? I guess another bad example? My bad.
