Restrict certain champions in Hexakills like how you did in URF

Let's face it. Twisted Treeline is a very small tiny map of all other 3, and cramping up with 6 champs could be a problem. I mean, yea I agree it's fun, but sometimes the spaces to move about would cause a lot of problems in terms of positioning & assigning a certain teammate to go and then gets rekt out of nowhere by a freaking AoE assassin ults.

Secondly, URF was made to be a joke for April Fool's Day, but for a few days later, Riot has taken it into account a lot more seriously, and started to ban more than 5 champs to being unable to play in normal games (even though they're accessible in URF bot games).

So actually, I prefer Hexakill to have either two different type of rule modes:

1. Restrict certain champions from the start.
2. Draft mode

Of course if we were to go choice 1, we do have to unlock Hexakill in Co-op vs Ai mode too. For choice 2, let's make an option if we were to either choose to go Blind Mode Hexakill or Draft Mode Hexakill, to make it fair for both sides of what they do want to ban certain champs they have in mind, instead of suffering to not have that champ they wanted right from the start (eg. Choice 1).

If I were to choose Choice 1, I would ban:

1. Katarina (seriously, enough is enough)
2. Talon (the ult ring doe)
3. Kassadin (he can actually ult through the thickest wall, like the one between base & altar. Too much escapes)
4. Fiddlesticks (due to the fact the map is too small to run away from if you don't have hard CC to push him off)

Hope Riot would take account into this information.
