I think it is about time we get some more role/class specific items

You have the few items like the smite items, the hydra items, and hurricane. But that is it. A reason why balancing items (like ragebalde, lethality items, etc...) seems to be challenging is because the wrong champions benefit too much from them. Every adc would love to have the hydra item's aoe passive. But because it is melee only, they cant. Same for how melees cant use the hurricane passive. If either were true, it would be op. So why not make a couple items which are defined by a few criteria (like marksmen, melee assassin, support, jungler, etc..). It would not hurt since those items would have a limited champion pool who could use them, which would make balancing them much easier since only similar champions could benefit or be harmed from it. It is also a way to make certain classes of champions uniquely strong in a certain specific way which caters to their play style.

However, I think just using melee and ranged as the only criteria is not enough. You get things like where it is made for assassins, but you have tanks like using it to buff their CC abilities or champions like who go full assassin because they are naturally tanky enough to deal a ton of damage (they have increased damage stats because they are more defense item focused) and can heal for full for free quickly once they are returned.
