Is ARAM truly random?
Sure it's an anecdote but... The number of times I've gotten Xin Zhao or some other melee champ far exceeds the number of times I've gotten a good ranged champ on ARAM.
I am also quite certain the number of Varuses, Luxes and Ziggs I see on the opposing team is significantly higher than the number I see on my team.
I think the ARAM algorithm needs a look over to ensure these insanely stompy comps don't happen to people as often as they do.
