ARAM - champions that should never be on it

I realise not many will care about this but some will. I tend to do ARAM when I'm feeling drained and just want to play without any real pressure but there are some champions that are just far too powerful on the map. Whether it's limited space, spammed abilities, massive area control or a combination of all of those they are never fun unless you are using them and even then you can feel bad. I have a few that I really can't stand and I will start with the worst offender.

Get grabbed? You're dead. It doesn't matter how amazing you might be at dodging because you are one of 5. He quite literally makes it 4 v 5 with one skill and I would be willing to bet he has a very high winning %.

A more obnoxious champion on a small map I cannot imagine. Now that Riot decided in their infinite wisDUMB to give his silence 7 bounces it doesn't take long for one this to chop down an entire team. Stay out of range? I'd love to but for such a powerful silence it has a pretty long range and he can afford to take a tower shot. Not like he has to worry about health.

A new hatred for this bomb rat. Towers are still weak despite their 'buffs' and when you add in that he now has a tower execute as well as his legendary lane stalling / pushing power and poke it makes the few towers you have even more worthless.

I'm torn on this one because I like Katarina but let's face it she snowballs stupidly hard on the map. Bunched up champions, little to no coordination = pentas for all \o/
