Changes in the game

Hello,
Always we think of new troops to evolve or defenses or heroes or balancing. But I should have something really new. Let some ideas to improve the COC.
First, you should have a challenge a week. It functions as the phase of the goblins. But the attack, the person would not waste his troops. Let the rules:


a) should have a number of evolve (these are the CVs convey that the person must pass or the number of houses).
b) Everyone will start on the weaker. Along the journey it will become more difficult.
c) Nothing will be spent. His troops will not spend, your heroes will not go dead (will as a friendly battle).
d) Depending on their performance, the player will receive a reward. This reward will be in gold, pink and black elixir elixir.
e) Is there a history in your profile, showing how far you could get.
f) should be made different from normal. May have 5 towers hell, 10 Tesla etc.


We will discuss and add something? We need to change a bit the way you play COC.
Thanks to all and a good game.
