what champions should i play in ranked??

When i play normals i usually get good , communicative teammates and just stomp on the enemies most of the time. When i try to play rankeds , my botlane starts feeding wayyy too early and my jungle decides just to jungle because ”his team sucks”. I tried playing the champions i play the most on normals yet i still lost everytime because somehow the enemies i get in ranked are SKT T1 level opposed from the ones i get in normals. Any op , annoying braindead champions i could play in ranked to make things easier??
