ARAM "random" selection?

This is NOT a real bug, just a personal comment on this topic. Maybe the ARAM champion selection is not so random as it seems. I have no idea which algorithm is used, but it probably doesn't work as you want to. I can say this cause i have played some aram matches, and i found that there are some "favourite champions" for the selection. In my case these are: this is not a rule but in the 60% of the matches the first selection is one of them, so i have to reroll or exchange with someone else. i have like 30 (or more) different champions but in aram i have to play sona and soraka every match cause this "issue". you can prove this just seeing my aram match history, and i ensure in most of them i have changed champion (but no one wants soraka or karthus XD). i hope you can investigate, and eventually change the algorithm so i could finally play more funny champions in aram ( ). thanks for your attention, i am waiting for updates ;)
