Idea for earning Green GEMS in attack

Hey! Guys I have heard many peoples who want to earn gem by a special mine or anything else but I don't think SC will add this feature to game.
So,I have another idea from which we can earn gem while attacking. The idea is Earning gem from gem box!
If we attack anyone who have gem box in its base the troops will also destroy the gem box and earn only 5 gems which doesn't cause high harm to the defender I think. The base which is destroyed with the gem box cannot be destroyed another time. It will only destroyed when the owner collect the 20 remaining gems! It will make the game more interesting I think.
THANK YOU

It definetely would not make the game more interesting.

Hmm... 😕😕😕😕 but nice way to earning gems. Isn't it?

Realistically, this idea won't help you get many more gems. Obstacles span every 8 hours, and give you an average of around 2 gems. You earn over 5 gems just by removing obstacles. You might only encounter a gem box once a week.
