When will thornmail get balanced?

Or when will an ad item come out that will better fight thornmail? You shouldnt have to build 4 items to counter one... I was fairly fed as Jinx. The enemy maokai had banshees, thornmail, warmogs, and randuins. They were an all ad team other then maokai and a really behind mid ahri. I had PD, IE, LW, BOTRK, BT, Boots and a red pot. I still counldnt 1v1 Maokai because his tornmail was still doing more damage to me then my healing. I shouldnt have to build armor pen, life steal and magic resist to negate the damage FROM AN ITEM. I mean seriously I was healing for like 124 hp per AA and thornmail was dealing like 140 damage per aa. I mean simple changes could make this item not as broken. Make the damage returned be a percent after armor/mr. Increase the armor or add like 150 health and reduce the damage returned to like 15%. But 30% on a full build(400+ ad) adc is ridiculous. Or make an armor pen item that has mr and life steal. If the enemy team has no ap threat I shouldnt need to build a magic resist item just for thornmail. This item has no counter unless you base your entire build around it. And no, having your team play around it isnt balance either. Because lets face it sometimes the enemy team out engages your teams peel so the apcs shouldnt haver to focus the enemy tanks and in this tank meta if your team has 3 or more ad champs or a single ad champ in your team gets fed trust and believe there will be like 3 thornmails on the enemy team. In the end all of the armor pen items other then LW are lack luster on adcs anyways(Black cleaver on anyone other then miss fortune and possibly ashe since her q's cooldown only gets lowered by cool down reduction is bad and ghostblade is the 1st item graves/vayne will sell when they have money for another item after they are full build) I mean seriously what was the last ad item released? Essence reaver? How often is that built? So please I hope to god a red will read this. Either release an item that will make thornmail(especially in a tank meta) not completely broken against mainly aa based adcs like jinx, sivir, ashe, vayne, cait etc or revamp its stats. I mean adding health and making the damage return calculate after defenses or add more armor and reduce the damage returned to 15%-20% would be amazing. I mean change the build path to two chain vests or a chain vest and a wardens mail, make it 120 armor and cost 2300 and have it return 15% damage would still make it cost efficient and strong just not game breaking because no item should be overpowered in itself. At the moment the only adcs that can combat thornmail are non aa based adcs and anti tank adcs such as corki, vayne, varus and kogmaw.
