Character based ELO is almost out of the question as that would require everyone to pick their heroes before joining the queue.. leaving the matchmaking system the wonderful task of sorting out 10 different Ezraels and putting them on 10 different teams.
You don't see that as a benefit? If I sit down and I only want to play for an hour and I want to play Ezreal, then having the option to select that is a benefit. Otherwise, I queue dodge until I get in first and lock in Ezreal, or I play some other character and don't have as much fun.
I contend Elo by character simplifies matchmaking and makes for better games because I'm paired up with others of similar Elo based on the character I'm playing. If I'm tryhard then I'll play my main character and be matched accordingly. If I'm trying out a new char, I'll be matched against others trying new characters (or trying the game in general, given that other limits on mm are still used, such as newbie island, etc.)
Another example comes in balance - Riot can go off and make an uber character and people who play that character will max out on Elo. Then, they can look at the numbers and see that Jax's average Elo is 2500 (no matter who plays him) while Warwicks is 1100. They can then choose what to do - keep it and MM will ensure that games will be fair or nerf/fix the characters.
