I'm really irked I can't ban Kindred from my own team

The Ban system wasn't made so that you could prevent your team from taking champions, it was made so that THEIR team can't choose certain champs that could break your team comp.

No, league's ranked system wasn't based on solo queue, it's based on Teamwork and communication.

Agreed, however one who is willing and able to put the time in to have the element of surprise with a new champion should not be punished for the actions of idiots who do not understand what you're saying here.

As I said to DrCyanide if someone is willing and able to put in the effort to learn a champion ahead of time (aka PBE) they shouldn't be punished based on the actions of idiots who don't understand how to properly play ranked.

Bans are for stopping the enemy team from having champions, not your own team. You can argue about whether new champions should be allowed in ranked all day, however none of it will impact the purpose of bans.
