Yes, that is a very viable option, and a common one, but with many champs where with your runes and the lifesteal, its very probable that you can farm/get fed enough to the point where you can get the infinite edge and boots on the first back, while having tons of last hits and maybe 1-4 kills. If not, and the other team seems to be competent enough, then most definately get that bf and boots, as it's much more versatile. But yes good, point, as that is also a common path, I shall add that in soon. Thanks for checking it out!

Spending 4k before getting boots seems very dangerous, I would recommend getting bf, then boots, then build Infinity.
Other then that, very nice build.

this build looks great cant wait to try it rate and comment mine please :)
