What a ridiculous argument. So let's make Ele and JT have 0 armour because technically no enemy unit should never be in range of them.
If 0 armour came with a turret? Hell yes! For similar reasons is why puma is a god tier unit. How much armour it has doesnt matter when you have the mobility and range not to be hit.
No one is saying having good Armour is terrible. People are saying that having high Armour, on a unit that is meant not to be hit, isnt a worthwhile tradeoff vs high damage, high pen, mobility and having a turret.
