Ranked Aram

Why is there no ranked Aram? I understand that the game is very much random based, but let's be real, it's less random than TFT. You only can get champions that you own so if there are certain champions you for sure never want to play in it, just don't buy that champion. Not to mention if you do get a champ you're not feeling you have up to two re-rolls plus your team has up to two re-rolls as well, giving you up to ten chances to get a better champion. I've heard that people will dodge if they don't get who they want, but let's be real they already do that in normal ranked. Just punish them for it like you would any other time. In my opinion, if you can't play a variety of of champs, maybe you're just not that good at Aram? I think that's pretty simple. You know people would have Aram accounts though anyway-only having champions that they feel comfortable playing. The best argument I've heard against it is that riot shapes character changes based around summoner's rift and not Aram or twisted treeline, and I'm going to be honest with you. Who cares? I'm not expecting you to shape a meta around Aram, the meta should be as a balanced as possible anyway right? So if the meta is a least impactful on the game as it should be, why not?
