User blog comment:Fistful of Force/Champion Concept: Pey-Yi, one who has walked through hell./@comment-88.159.13.170-20130206151133

This champion sounds like a rework of a noctune, rengar or talon. You go in assassinate your target and use your abilities to reposition and block/escape from damage. I cant see how this champion is any better than twitch. The champion has a lot of  short duration movement speed buffs, which are pretty useless if you are slowed, (most slows last about 2 seconds).

I would replace the movement speed buffs (leave that for support to do for you with shurelya's) for attack speed buffs. If the passive of e increased attack speed as health was reduced that could be interesting. If  you max this ability first with a bloodthirster as first item, this would be a very powerful trading tool. Enemy champions might consider items that reduce the effectiveness lifesteal or even run double ignite bot lane.

The passive just sounds like blade of the ruined king. This passive would be very good at poke in lane, but rather useless in team fight. So this would reward playing safe and dominating lane and getting an advantage that way rather than going all in and engaging and getting kills. Sounds like caitlyn, get kills when enemy is low rather than bursting them. Poke bot lanes are boring.

Plus with the shield the enemy cant stop you escaping after you poked them because of your shield makes you invisible allowing you to just walk away.
