This has been gone over, and has been rejected by devs in a different form called war crystals. Now my new idea. Troop and spy regen crystals. You can use 12 each a day they would cost slightly more than xstals at .55 usd each which is .1 usd more than just buy xstals which you could still use 24 of each day Anybody run into a all attack eb or all spy eb knows how nice this would be
Actually this is a crystal idea I like. Thread needs a little more effort but nice job. I have been in situations it be nice to only fill up one bar
It isn't complicated. Just refund xtals at end of the war. It is already implemented in game. Devs won't do this however and abandoned this idea. It's all about the $
