Why is every single Duskblade compensation a nerf?

Wasn't the idea to nerf Duskblade so you could add power directly back to their kits? Instead we got:

.8 AD per level. From 3.2 to 4 Wut? 14 AD at level 18? Even MF gets a full 1 AD per level? Can't even have as much as the ranged carry? For that he gives up 240 damage on his combo plus an even further gimped early game? A champion that is notorious for his dogshit early game is getting compensated with a scaling stat that still results in a damage nerf anyway? It's even base AD so it doesn't even apply to his E.

gets 25 base damage plus an extra .15 ratio on his ult. Let's see. That means you only have to have like.......... 1400 AD to make up for losing that 240 damage. Seems reasonable. Oh, and zero compensation for every time you fight without your ult.

an extra .1 bonus AD ratio only on the return of his rake. Well you only need 2400 bonus AD to make up the difference in his all in. Right. Got it. Seems fair.

plus 1 AD per level. Hey! At least you got more than Wukong! Can't mess you up too badly before that legendary "ultimate" skin you have coming.

truly meme level "buff". Minus 3 AD at level 1. Gain .6 AD per level. ??????????????????????????????????????????????????????????????????????? You know what? I'm just gonna give you the benefit of a doubt and assume you're going to add something else. Please. (Edit: yes there is )

an extra .1 bonus AD ratio on shuriken. Oh, and and extra .06 ratio on secondary damage. Even if you land a triple shuriken, you still lose damage on your all in. Huh?

................. Nothing kappa

Are there more plans besides these changes? Because it seems like every single Duskblade user is getting nerfed with these changes. How is this supposed to help any of them with doing their job? Every single one of these champs will still build Duskblade every single game except they're just nerfed now. Legitimately every single one.
