My 2 cents:
Remove simoleans from the chests at the end of war. 7,000 simoleans over card upgrades is a terrible “reward”
Agree with the platinum key point also. Aside from a few buildings, they don’t do much for me.
There has to be a solution for teams sitting shielded for hours upon hours. I’m in the middle of one right now, and we’re winning by 14k... they’re outnumbered 2 to 1 and we’re all going to be around the last two hours, so I have no idea what they think they’re going to accomplish. Perhaps the answer is an energy boost for being unsheilded or penalty for being shielded over a certain amount of time, such as you’re unable to launch an attack for x amount of time once you remove the shield, and perhaps degenerative energy over however many hours and then it just auto repairs everything at zero. Reasonable time lengths to let people sleep and work a little...
