Why isn't Dead Man's Plate geared more towards juggernauts/being anti-ranged?
It seems like you could easily do this.
Dead Man's Plate
Giant's Belt (1000) + Chain Vest (800) + 1100 = 2900
+425 Health +60 Armor
Unique - Dreadnought: Generate Momentum while moving (max 100 stacks), granting up to 60 bonus Movement Speed. Momentum decays if you become immobilized. While you have maximum Momentum, you take 10% reduced damage from enemy basic attacks.
Unique - Crushing Blow: At maximum Momentum, your next basic attack will discharge all Momentum stacks, dealing (120% Base AD) bonus Physical Damage. If melee, the attack also Slows your target by 50% for 1.5 seconds. Basic attacks will discharge 15 Momentum if not at maximum.
The added basic attack resistance at maximum Momentum primarily affects melee into ranged. Melee into melee generally won't resist more than one AA due to having to be in each others' faces to AA, and if a ranged champ were to use this DMP, they'd probably just discharge the Momentum before it had time to do anything.
Making the Crushing Blow scale off base AD pushes it towards juggernauts, with their high base AD and easier access to Sterak's Gage.
If you were wondering how strong 120% Base AD is, as an example, Illaoi @ 18 with Sterak's would deal 276 damage.
Keep talkin....

I'm all for it
