Revenge : Show if shield is active or not
I NEVER use revenge because:
Whenever you want to revenge you prepare a suitable army, an expensive one specially designed to beat the often higher level enemy. Then you press the button and get (98% of the time) user has a shield or user is online.
Result: You throw your full dragon army on to an enemy that's worth 1/10 of the cost of your army ... pure loss and tears.
Revenge has a very bitter taste because it cost me 10x more than I got out of it.
Waste of my time and actually the guy who attacked you stole twice from you ... where's the revenge in that.
If you want to improve the game and ask me about priority, fix this before anything else.
I don't want a timer to see when the shield will go down, but at least show us that you can or can't revenge.
There's still the chance that someone else was before you since you need to build your army and that takes time.
You'll probably even sell gems because you want to accelerate your barracks ... this is a win-win situation guys.
