Can we make Duskblade the I.E/D.C/Cinderhulk for Assassins?

Maybe its just me but i feel like this item isn't providing the stats it should for being what riot initially wanted it to be. Back when the item was released, A LOT of assassins were building crit.. Youmuus had crit, which was around the time that Youmuus-I.E Zed was popular. Then they released this item to hopefully give AD Assassins the equivilant of the ADC I.E and D.C for mages.

55 AD 35 MR Spell Shield 20ms ooc -15 Lethality- 3100g 60 AD 20%ms 10% CDR 20ms ooc -15 Lethality- 2900g 65 AD True Dmg on-hit auto sweeper 20 ms ooc -15 Lethality- 3250g

Sure it gives the most stats.. As it should. My question is, why doesnt it give the most -Lethality- When thats kind of the idea behind buying the "super lethality" item. I mean.. if you buy D.C you get to give all your other AP items a big boost, Your I.E gets to increase all your AA dmg, your cinderhulk stacks up your hp.. I know not everything should be balanced the same way.. But why can't we take 5 AD off for 20 Lethality? Or increase your Lethality by a % instead of giving you like 100-175 true damage to your combo.. Better yet, if im using my or run up to a spot that has a can we PLEASE make it so it won't trigger_ Blackout Passive_?

Not going to say i have a perfect solution, nor will i say that its a huge issue. For me its missing the mark as the Ultimate Assassin Item.

Edit: Also notice how seems to be the best assassin item? I know riot has had an issue balancing this item.. but its seriously crowding out the lethality items, probably making it hard to make lethality items strong too. Maybe it needs a bigger rework than what Riot is doing to it? Make it Shred Bonus armor? Wouldn't that possibly make buffing Lethality less scary? idk, just my 2c.

Edit 2: Patch 6.3 it was Released, here is the context: NEW Duskblade of Draktharr New item for assassins. Basic attacks give a mini-death mark on your target.

It's well known that many AD assassins who relied on attack damage items took a hit with the transition to 2016, especially with the changes to Last Whisper. These days the 'core' item build that feels good often only goes to 'build Ghostblade and Maw and hope that's enough to finish them off.'

Balancing around core items is something we do for every class, but assassins have been left in the dust - forced to scrape by on whatever the best damage items happen to be, making our balancing points for them somewhat… very inconsistent. Duskblade means we can give those folks a core item that not only helps multiply damage in a full build, but also offers a clear expression of power for those with a gold lead.** marksmen have Infinity Edge, mages have Deathcap - and now, assassins have Duskblade.**

Duskblade's passive, Nightfall, provides a different angle for assassins to contribute meaningfully in a teamfight. Missing health damage is unique in that it can be considered a damage amplification for your team - capitalizing on all the work your allies have done so far - allowing assassins to feel more capable on clean-up duty and less pressured to throw their lives away in pursuit of bopping a marksman. BUILD PATH Serrated Dirk + B.F. Sword + 850 gold TOTAL COST 3250 gold ATTACK DAMAGE 75 BONUS MOVEMENT SPEED 5% UNIQUE PASSIVE +10 Armor Penetration UNIQUE PASSIVE Basic attacks on an enemy champion apply Nightfall (120 second cooldown) NIGHTFALL After 2 seconds, Nightfall deals physical damage equal to 90 + 25% of the target's missing health. If you get a kill or assist on the target before Nightfall detonates, the cooldown is refunded.
