Yeah that's what I've been saying, getting zeroed out is extremely disheartening. You pretty much have to keep your army out all the time, and make sure you're only ever hitting someone with overwhelming force
I tried adding phased caps that limited damage at long range to .15, limited mid range to .25, limited melee to .40, and that helped ease the destruction on both sides considerably. The caps were phased to prevent a scenario where people might go full long range and just turtle up, and also add realism. I also thought if people lose fewer troops in battle overall, it would encourage more battle, which is fun.
But my idea was not agreeable by most so that change was rolled back. I guess getting zeroed out is closer to how the game used to be - though I don't remember it being that way. Maybe it's how things evolved in the later rounds that I didn't play in or something, idk.
