These champions need to be addressed fast

The level of damage I've noticed through so many games from these four is disgusting.
needs to have his after effect time bombs removed.
needs his damage nerfed hard. The levels he's doing with just hp items and tank items is ridiculous. I've fought one last week who took 2 ignites, mortal reminder, borks, etc. and didn't lose almost any health. It's disgusting.
Fizz is just toxic at this point
revert her fucking revert. Wtf who thought 1 shot leblanc is okay.

Udyr needs to be addressed too. Not overpowered, but just toxic at this point.
