Youmuu upgrade feels weak.

I feel like the youmuu's ghostblade doesn't give a powerspike like it used to. The gold efficiency of this item is just 100%, but you build it from a warhammer, which is 104% gold efficient. So whenever I upgrade Youm, it's like I'm paying 75g for the active. But the thing is I want moar damages, I don't want some lame AS or MS. I can buy duskblade, it is almost gold efficient AND I get a dmg passive.

Edit: Okay, it doesn't look like I provided enought context for my statement. I usually get Youmuu's on my Crit-yi. When I go crit Yi, I already maxed my CDR from essence reaver and warrior - and the build usually only has enough room for one armorpen item after zeal-warrior-ie-er-boots. I still go youmuus bc it's build path is pretty good, but lately I been tempted to just keep it on a caulfield's warhammer or skip it and go duskblade. You might say AS and MS is pretty good on Yi, and it sometimes is. The youmuu MS active is one of the few reasons I still build it, but the AS usually goes to waste unless I'm fighting a tank bc carries just get 2-shotted. Now, youm's was probably OP considering I built it while wasting the CDR. But consider the opportunity cost when rushing a youmuu's: on mobile AD assasins, the active goes to waste (no point in AS, MS is conditional), whilst buying a duskblade gives you permanent MS and a strong passive. But I still want to rush youmuu's bc it's build path is so damn good, but I feel bad finishing it b/c I don't provide more damage for the team.
