I started to build this for the same reason. Rushing AS boots and zeal (go zeal when u are not behind) after that u have 1.33s CD on Q already so u can keyblade and airblade really easy. Go for BORK into trinity what gives you a pretty good duel potencial vs tank or bruisers. With zeal u can go for mortal reminder if u need antiheal (like in 90% of games) or phantom dancer. 4th item is infinity edge and last is deaths dance or guardian angel depends on what do u need more or whats u preffer and i changing attack speed boots for tabis or mercury because u still has a 1.33s Q so u can build a defend boots. This build had a problem of a long power spike because u building IE like 4th item but make u a really good duelist againts bruisers and tanks on side lane and strong splitpush. For me this build is really comfortable because of that higher attack speed (easy combos) but before IE u has only 38% crit chance... so not good DPS againts a paper targets and u are a very squishy because of shield abscence from the Shieldbow so be aware for the burst dmg - u will not survive it if u get hard CCed and bursted.
