He's been kind of a niche ADC for awhile, but the more I play the more potential I see, especially with the new BotRK. I've been building him like Tristana and it's been working pretty great.
Sure there's the whole issue with having no escapes, but I'm of the opinion that a spammable stun, no mana dependence, and a global presence make up for that. --- Cooler than Freddie Jackson sippin' a milkshake in a snowstorm.
The only way I've played him outside of normal AP is building manamune and icefist as core. Spam skills to charge manamune and proc icefist, blue cards to keep the mana up. I only do it on ARAM when my team lacks AD, but it might work on top lane. Good kiting ability and consistent damage output, can be really fun.
If you crit with the Underworld Twisted Fate skin, it makes this awesome banshee shriek noise. I see this as encouragement to play him AD. --- The time is out of joint. O cursed spite, that ever I was born to set it right! http://i.imgur.com/pyvQmyz.gif
