This is needed and is the number 1 reason why people will leave the game, and why many have already left.

The game rewards high level players for farming low level players. The game offers no mechanic for new players other than rebuild completely every time someone stronger destroys 100% of your units with less than 1% of their income.

The natural result is far fewer players staying until you have nothing but a small number of higher level people playing a dead game.
