Should ARAM have bans?

Now I know this sounds silly since the whole point of ARAM is to get a champion at random and just play with it, but I always seem to get games with one team having an overwhelmingly powerful team comp (for ARAM) and the other having a far lesser team composition. Another annoyance I have observed is that some champions seem to appear much more often than others, for example Sona who is almost guaranteed to carry her team because she is so broken in ARAM. I believe this leads to often un-fun gameplay in a game mode that is all about having fun and taking a break from ranked stress. I think a solution might be to introduce bans to ARAM, to remove some of the over powered champions, perhaps 3 or 2 bans per team? More? Less? Anyone else share my thoughts?
