I don't think SC has ever said that maxing a base is the 'correct' way to play the game.
Many people say that maxing is the best strategy. There are good reasons why, in war, there may be advantages to rushing if you do it right - it gives you more choice of what to build. Of course if you rush you get the loot penalty in multiplayer so it's harder to upgrade.
It's advisable to max, not a clash law, there should be no penalty for not maxing, its strategy, not following like sheep![]()
