[Champion Concept] Zinc; The Battle Ready Blacksmith (an AD support/fighter concept)

I would really love to make an Attack Damage focused fighter support class that league doesn't really have at the moment. I think a blacksmith would fit this hole nicely. I have tried my best to make a support that would benefit from stacking Attack Damage without the champion being over powered in a solo lane.

Name: Zinc

Story:

• Olaf's war buddy (whether he was born in Olaf's region or if he traveled there is not decided)
• Refuses to wear any amour he hasn't made and he hasn't mastered how to make a helmet hence he wears no helmet

Visual:

• Dark skinned (anywhere from Inuit to Ekko on the skin tone spectrum)
• Heavily armored without head gear
• Wields a two handed giant hammer which he could hit an anvil with when he backs

Class: Fighter / Support / Tank

**** Passive: Battle Scars **** Zinc gives W attack speed and X health regeneration to all allied champions in the area (including himself) for Y seconds whenever he uses an ability on a champion (stacks Z times)

**** Q: Hammer Time **** Zinc slams the ground with his hammer creating a fissure that deals W damage and knocks up targets for X seconds and then slows for Y seconds. Zinc is slowed for Z seconds. ( I think the area of effect could be in the shape of a 'T' ) ( This move could scale on Attack Damage )

**** W: Inner Strength **** _Passive: Zinc builds up inner strength upon taking damage. Active: ^Zinc releases his inner strength in the form of a war cry. All surrounding allied champions increase their movement speed by (X per inner strength) armour and magic resist by (Y per inner strength). ^^Additionally zinc gains (Z per allied champion in war cry) attack speed. _ (^This move could scale on Armour and Resist ) (^^This move could scale on Attack Damage )

**** E: Shield Sap **** _Zinc targets himself and an allied champion to be shielded for V damage that lasts W seconds. If the shield is popped it deals X damage to nearby units and heals Y health to the ally over Z seconds. _ ( This move could scale on maximum health )

**** R: Fist Fight / Death Hug / Iron Maiden **** Passive: Zincs basic attacks steal U% of armour and magic resist from champions for V seconds stacking W times. Active: Zinc dashes and grapples a nearby enemy dealing X damage and causing them both to be suppressed for Y seconds. Zinc and his target gain Z% damage reduction during this time.

( This move be a targeted without a dash or a skill shot with a dash but through minions, if he misses the cooldown could be shortened )

Any suggestions?
