I agree DEWO. Couldn't have said it any better myself.

And btw, i read your guide and liked it.. but, even though its completely up to you, i think the point in utility mastery is better than greed, because if you had for example a 30 minute game, greed only nets you 180 gold.

Why the hell ppl try to equip Yi with Yoyo all the time. I know it's a new item, it's shiny and has nifty activate but...
30AD - less than wuju style passive gives...
15% crit - nice but for that price?
20ArP - this one is nice but... again price?
Active - why do you need a 2nd Highlander? It ****in resets on each kill... lasts longer, gives more AS/MS.
With Yoyo active you will go waaaaaay over AS cap meaning wasted stats.
oh and cdr... well, your Alpha is nice to initiate and it will be ready to last hit a fleeing enemy, Your Wujustule active lasts long enaugh to kill a whole team and even longer, meditate cd... ? ok skippin this one. Highlander? it resets all the time.

So you buy a weapon witch is not a big boost for yi in terms of damage, for a price of 2700g. for that Price i can buy 2 parts of infinity edge, +50 damage +18% crit.
I loose the ArP but i dont waste slot for better items.

I would vote for that item on ppl that are cd based, and dont need lifesteal (trynd for example) Yi imho doesnt need Yoyo.

Ghostblade is great, but costs more than executioner's calling. I don't feel the speed boost compensates for the delay in the build, but it's completely up to the player's personal preference.

I am not so sure its just an "okay" item, ghostblade is amazing for nearly any melee dps, and at that, yi is a perfect candidate. This would give him 2 huge speed buffs at his disposal not to mention the actual stats on the item are good for him.

Yeah Youmuu's ghostblade is an ok pick in place of executioner's calling in some cases, depending on your opponents. The lack of early lifesteal kinda sucks though.

Any Yi build w/o Youmuu's is bad imo.
