The people who start our earth wars recently told us rather suddenly that they need ALL four types of essence in order to keep declaring war. Sure enough, when I looked, all their tanks were mostly empty. I don't know how much they had before they told us they ran out, but given that their non-health tanks were 100% full the previous time I looked before they asked, I was a little surprised that they ran out out all four essences without having nagged us to fill their tanks earlier. I know they declare a lot of earth wars, but their health tank has always been lower than the rest, and earth wars would use up essence evenly, so if it was only earth wars, they would've needed more health essence before the other types ran out, but when I looked, all of their tanks were very low, and in fact, their defense tank was at 0, while health had a few thousand.
I don't know for sure if all their tanks got emptied out suddenly, but I thought it was very odd that their defense tank was lower than their health tank. If all their essence just vanished, it would explain how that happened.
