how to fix the turret problem

right now turrets are damn near non threatening. with such low armor and the platings that fall off making them more vulnerable. i think what should happen is the outer turrets keep the plating but make the inner turrets have more armor and magic resist and the more in you go the more they have. right now outer turrets sit at 40 Armor and MR which translates to ~30% less damage. then after the plating falls off both armor and MR drop to 0 and they turn into paper. the inner turrets and back have 55 Armor and MR which is ~35% less damage. what should happen is the outer turrets keep the plating and such the inner turrets have enough Armor and MR to take ~35% less dmg. the inhib turrets have enough Armor and MR for ~50% less dmg and the nexus turrets have enough Armor and MR for 75% less dmg. to offset this (not saying balance cause Riot don't believe in that) no turrets will have health regen and have smaller zone of control (500 ft compared to 1000 ft) . the reason for this change is so that turrets will be tougher to destroy and will require a full team to attack/defend it. making it less likely for split pushing and soloing. why not just increase damage the turrets deal? well cause every champion and their grandma can fart on a turret and destroy it and only take one to two shots which would be at most 250 damage with how tanky champions get mid game.
