I've tried her as a support a few times, and it didn't work out for me. Even if you level her E first I find it still doesn't do enough to protect the carry. She doesn't have quite enough range to add additional harass without taking damage herself either. In terms of team work, yes she is an awesome supporter. I save as many lives as I take it seems. She is an underrated mid in my opinion. If you play her smartly you can come out of lane against anyone without dying and still getting a ton of farm. She doesn't snowball as hard as other champs, but she doesn't flop either. Don't expect to single handedly carry games, you need a strong damage dealing team to finish your kills for the most part. So, she's VERY fun to play, but I don't think she's going to get me out of low ELO.
