Tank item concept Warlords Boneplate of Unholy Bloodlust

So i wanted an item which scales well for tanks This item would not be as effective as a randuins omen or deadmansplate in the early game or midgame but can outscale them.

These are the stats so far

Warlords Boneplate of Unholy Bloodlust 600 health Reduces physical damage by 10% Unique passive; Boneplate: Gives armor equal to 1,5% of maximum health Unique passive; Unholy Bloodlust: Whilst in combat gain increasingly more health regen up to 300% bonus health regen ramping up over 10 seconds and decaying over 10 seconds when out of combat for more then 5 seconds

The two unique passives are unique for obvious reasons, otherwise people would just stack the item, which can still be done for the damage reduction part kind of like how you can do with randuins but its not really optimal to say the least.

The ramping up health regen will allow tanks some better in combat sustain, because tanks generally have higher health regen then other champions this should also keep other champions for getting it for that reason. It's just best on tanks, and the same goes for the health scaling armor, Since tanks tend to have most health, again this item would be best on them. This should help prevent abuse cases a bit and still make this item great for tanks. Ofcoarse other champs can use it too its just slightly less effective.

To give some context, the 300% health regen from Unholy Bloodlust is about the same as spiritvisage will give you at all times. needless to say this item would synergise well with spiritvisage. As for the other passive, Boneplate, with 4000 hp you would gain 60 armor, so thats about as much as randuins gives.

Warlords Boneplate of Unholy Bloodlust synergizes very well with the following items Magic resist health
Armor

Champions it would synergize welll with would be those who can make good use of the afore mentioned items and scale well in health and healthregen, mostly tanks and the ocassional juggernaut which is basically a tank without cc/utility but instead has damage so there is some overlap there

Anyway this is still a work in progress but i wanted to post it because i am curious what you think of it
