Changes to ARAM Please Read

So after giving it alot of thought I believe I had some ideas I would like the Devs to possibly consider for ARAMS but before i get into that let me explain it all. So today while i queued up for arams i got a champ i really wanted to play and someone wanted to trade me but i refused. That led to the game closing before it even began and I was had to re queue. As i re queued I got stuck with a champ I really didnt want so i re rolled twice and just ended up leaving the game and taking the 15 min penalty. This way of game design/gameplay is just not rewarding and very annoying and makes me feel like I shouldn't play league. Now I know by design the game is random. I however may have an idea for that. Instead of everyone being forced to re queue why cant the timer be paused and the next available person be picked and put in place of the person that left. The champ will still be random that way you basically would keep your champ and not take a penalty you don't deserve because someone basically forced you to use your re rolls which I sort of have an idea about that.. Again keep in mind i know its random so as you know when you queue its random however you can get stuck with a tank with both your re rolls i believe this system needs a diff approach ..my idea for this was when you re roll if you queued tank your first re roll wouldnt be tank however if you are unhappy with your first re roll then you risk your next re roll as a tank possibly ..but it would work for any thing really if you queued as a jungler then your first re roll wouldnt be jungler but your next could...i just think the fact that you can queue into tank and then get the next 2 rolls as tank and the next 6 games as tank is bad like and it doesnt seem random..so that my idea Also Please fix the bots being in ARAMS they are ruining gameplay ...So if you are going to comment keep it respectful dont troll and no i dont want to start over .. thank you for your time
