This champions 
immune from nerfs.
Take care to soloq.But your trouble is only competitive and money.
''We didn't see Fizz at competitive so Fizz is fine champion.'' But they don't forget.Fizz 30% ban rate and still no nerfs.
Riot logic again.Riot's double standard again.
Edit:I'm not hater.I'm trouble is strong and op champions.Some people said ''Lux hater, Ahri hater'' etc.I'm against op champions.
IWrath5 votesFizz is easily countered, so are Ahri and Brand. Well Brand might be a touch on the OP AOE side of things but still they're manageable.

According to your excuse Azir is manageable.

Dude they're completely different champs with completely different kits. They don't need nerfed, nor do they need buffed.
blfUvZ8Ybu2 votesStill isn't excuse.We don't nerf a champion with his/her kit.
This three champions are strong or op and need nerfs.
