A defense for TH8

Hello Clash of Clans Team, I love the game, I get used to any change you make in the game, almost never complain, but I want to let you know that every TH level has a new defense except TH8, idk why you haven't noticed that, and if you already know this I want to know if you may put a new defense for TH8 maybe a megacannon or something you will know what to put, they deserve it, it would be great to have a new defense but not for a TH that already have another defense, also the Ice wizard from clash royale could be a great dark elixir troop in TH10 or TH11 for COC but not to paralyze defense as Ice spell but slow the damage per second, the deployment slot may be 6-10, you definitely will test how is gonna be best, not to be OP (over powered) nor weak, also definitely the valky is better now than before, thanks for reading me and thanks to supercell for making COC, CR and BB... I only have supercell games on my phone
