Idea: Being Able to Remove Champions from Your Pool

I'm not adamant about this concept but I just think it is worth putting out there because I believe it would be relatively simple to implement but very effective in my gameplay, and I hope other's gameplay as well.

I play a lot of ARAM because it's fun to mix it up and just have a non-serious, 100%-fun game once in a while, but whenever I roll a champ that I really hate playing it just gives me 15-25 minutes of grief wishing for the match to be over. Champs like this are, for instance, Amumu, Annie, or Nasus, that I just don't find fun to play, especially in ARAM. What I am suggesting as an easy and fair fix to this problem is to create an option where a player can "refund" a champion, but without getting the IP back that they paid for the champion (hence the quotes around the word refund). This would just remove the champion from being a possibility in ARAM unless they are free. If you have dead champs that you hate playing in your champion pool (I bought Amumu in my first year of play because I needed 16 champions for ranked and received Nasus from a mystery box), there should be a way to remove them if you've already used your three refunds, because all they are doing is making every few ARAMs a nightmare. Even if you had to PAY IP to remove a champion from your champion pool, I would gladly pay thousands to never have to play some eyesores again. I am taking the time to make this post because, with the announcement that every player who has played recently will be getting Kayle and Riot Kayle for free as a celebration of Riot's 10-year anniversary, another champion I don't like playing will be added to my pool against my will that I can't give back.

I hope this post can get noticed and perhaps even made a reality because, to reiterate, it seems like it would be easy to implement but would have an incredibly positive impact on my League of Legends experience, especially when it comes to ARAM. Thank you for reading.
