Clash of clan challenges

Every week there should be a challenge so we get extra resources. Also if you complete challenges every week there would be a multiplier like week one get 3 more stars in goblin campaign reward: 40000 gold 100 dark elixir and 35000 elixir and if you complete it and week two will be say earn 20 trophies reward 80000 gold 200 dark elixir and 70000 elixir and u can only do 3 in a row so it won't be too much rewards. Also regardless to this topic can you add 4 more dark troops like warlock,werewolf,zombie, and best of all the dark lord,the cousin of pekka. Also add a new hero like Skeleton Warrior or Skeleton Knight and make it cost twice as much as you'd pay for archer queen, and make it do 120 damage per second and that it targets defenses first then storages.
