My Favorite League of Legends champion

Hey there everyone, ever since i was new to League Of Legends i had always wanted to know who was the strongest champion in the game that costed 3150 IP { currency in LOL }.Now after playing this game for half a year and playing every champion { except Diana and Yorick because i never got a chance of playing them on free week .}Now most people will be saying things like their is no best champion and it all consist of play style i 100% agree , although their are some super strong champions in each lane that only their counters can beat, these champs include , for top lane : Garen , Irelia , Riven, And Fiora . For jungle their is Master Yi , Shyvanna , Elise , and Lee sin. For mid lane the champs include , Fizz , Yasuo , Ahri , and Diana. For bot lane i will only measure supports because all marksmen take skill to get used to the supports that annoy everyone are , Blitscrank , Thresh and lastly Janna. Now those are only the most overpowered champions in general becuase they do a decent amount of damage have so much utility and can be super strong in team fights.In my oppinion the strongest role to carry the game is mid lane and in my opinion the strongest mid laners are Talon , Ahri ,Vladimir and lastly Annie.
