Is my idea a good one?

Nerf items that bruisers/tanks go to be tanky and still deal so much dmg.That way,they will still be doing that job of providing cc/peeling for carries(maokai for example) and bruisers will still dish out dmg. Nerf assasins mid game and translate some of that power into late game.Seriously,its so hard to get to a any adc that has okay positioning+his support peeling for him.That way they wont roflstomp adcs that fall behind mid game and will actually have counter play and still be relevant late game. Nerf support items and overall healing/shielding.Ardent cester,even after nerf is pretty OP.Locket gives a huge shield,redemption,although it has a delay can heal all 5 of your teammates for good amount of health.Knights vow buffs your adc/mid a lot.Nerfing that would make easier for enemy team killing the back line without having so much hard time just clicking them.Which leads me into the finaly point. Adcs,nerf their mid/late game,via nerfing overall crit and their AOE dmg.Also,if tank items were to be nerfed and dmg of bruisers/tanks,you can also nerf lord dominics and botrk without worrying about adcs dealing so little amount of dmg to them Your thoughts?
