Revenge

I've seen earlier threads about revenge attacks saying that you should be able to attack someone even if they had a shield as well as saying that you should be able to be alerted when you are able to revenge, but I believe that would be too much and works be very detrimental to the game. On the other hand something should be done about the Revenge. It's always a big guessing game on when the village owner will log off or when their shield will be up. I believe that there should be a green or red shield next to the players name in the defenses inbox (much like the "opt in/opt out" feature) to show who you are able to attack or if they are on/have a shield. And if they do have a shield there should be something telling you when the shield will be gone like "10h 12m shield" or something along the lines of that.

With all of these people zapping my DE I never get the chance to get it back because they are always protected by a shield that never seems to end. And guessing it's not very accurate so I don't feel it is fair enough that we don't get a chance to take back our resources.
