i would not call her 1-5 unsafe, i very rarely come out behind in lane. i feed in the 8-14 range when mid and jungle have all their killing power and mobility and you're still typically pre-zhonyas or rylais.She's just as strong in every other mode. It's learning to not feed away her relatively unsafe 1-5 and high early mana costs.
unless you're already way ahead from lane, then you turn on your playlist and go find those mids and jungles and have a nice chat.
