Revenge would not break your shield

So I've beaten all the goblin levels and now I have no way to play the game that won't break my shield. The single player campaign was a great way to still have fun playing COC while being able to keep your shield. And yes I know that clan wars alleviates some of that problem but that's only for two attacks (that you may never receive the fruits of your labor from) and also only for a 24hr period or every other day if your clan fights a lot.
So my idea (which I did search for but found nothing so sorry if I'm not original) is to allow you to revenge someone without breaking your shield. I see no down side to this and would love to see it added in future updates.

This would make attacking someone suck so bad. They could attack you right back without worrying about losing their shield. Sorry but this idea is bad.

Sounds a bit unfair but you shouldn't be afraid to break a shield anyway. If you attack a lot but don't leave much to your storages you have nothing to be afraid of, you won't be steamrolled all the time. If you just sit behind shields you're missing out on lot and frankly won't progress much further than the first few THs unless you're willing to either gem or wait for extremely ​long times for your collectors to churn you resources
