How are my favorite champs doing

I will maybe return to this game depending how my favorites are right now. My list is

Quinn, Diana, Irelia, Leblanc

The patch notes tell me leblanc is still lebroken which is cool but what about the others. I don't really care how good they are I just want to know if any are considered troll picks nowadays like am I going to have to mute my team if I want to play these
