[Champion Idea] to propose something with a mechanic of interaction with minions

For now no champs have really used the minions or have an entire kit based on them, so i came up with this champ. Honestly i have not thought about the lore, the names of the abilities, the name of the champ itself (i will call him "Champ") or the CDs or man costs, i just want to propose some abilities which i think will be cool to see in the game to explore new mechanics.

Passive: All allied minions in a rectangular area in front of Champ gains [10% of Champ Bonus Armor] Bonus Armor and [10% of Champ Bonus Magic Resist] Bonus Magic Resist. The area is 500 units long and 200 units wide.

Q: For 1.5/2.5/3.5/4.5/5.6 seconds all allied minions in a radius of 500 units from Champ will attack the target enemy unit dealing 5/10/15/20/25 [+30% Bonus AP] bonus damage on hit. This bonus is applied to each minion.

W: Champ gets 1 stack for each allied minion who dies in a radius of 500 units from Champ up to 25 stacks. When W is activated the stacks are lost and Champ summons in front of him 1 minion totem per stack. They will absorb 50% of the damage dealt to non-champion allied units. Reactivating W within 2/3/4/5/6 seconds teleports the totems to a target location where they detonate after 0.5 seconds dealing in a radius the same damage they absorbed [+10% Champ Bonus AP] each. The radius is 50 units each and the totems will automatically position themselves in lines of max 5 totems. Each totem can be destroyed with 3 hits and if W is not reactivated within the time limit they will detonate where they are.

E: Champ summon an Altar from which will spawn 5/10/15/20/25 minions every 50/40/30/20/10 seconds. Altars can be destroyed with 5 hits and E cannot be activated if an Altar has already been summoned and not destroyed. Reactivating E makes the Altar disappear or it will disappear automatically when Champ has not enough mana (it's a continuous mana expenditure like Anivia's ult).

R: Champ summon 2/3/4 super minions with 10% [+1% for each 50 Champ’s Bonus Health] Bonus Health dealing 20/40/60 [+50% Bonus AP] bonus damage on hit each one. They will automatically attack Champ’s same target.

Clearly when not in lane he depends completely on his Altars sooooo maybe this kit is a bit too much unbalanced in this sense, but it's practically a guaranteed win in lane cause of all the pressure this kit can make on the enemy turret. What do you think about it?
