As I tested it , I feel it ' s better going for the early movement specially since it ' s cheap cost allows you to buy basic boots and lethality since around lvl 34 is where it really starts to kick in , which is a pretty standard time for first backs . I guess BF is a good choice if you ' re absolutely dominating the enemy and want to cheese the lane out , but it hardly makes a difference . Dirk boots W allow you to roam to mid lane , contest early objectives and easily travel through the map in general while providing almost the same damage BF does . Regarding runes , going for lethality turns you into a scaling monster due to the amount they provide . It also allows you to poke the enemy bot lane for massive damage from lvl 34 onwards , and helps you do some RIDICULOUS damage lategame . Also , this build focuses heavily on AD items , so you won ' t really have an issue on discarding AD runes . Your base AD is pretty low , yes , but Love Tap and Q will help you farm and poke without any issues at all early on , just enough to let lethality start doing it ' s job . EDIT bit of formatting , and fixed some mistakes .
