Mistakes, fails, and blunders that we make in the game.

Among those that aren't legendary (like splitting equipped bracers, on your own territory, forgetting artifacts in chains, and so on), the main blunder I remember from my early days playing as Conflux. In translation, probably "Huts" — the buildings don't display their upgrade level. As a result, I kept accidentally upgrading either Ice Elementals or Fire Elementals. In the end, the Phoenixes just won't rise...

Also, I used to often get annoyed in Dragon Utopia when the enemy rushed straight into my first stack and I ended up wasting my own troops on the retaliation (same in Dragon Fly Hives).

And I won't even mention misclicks. (I had a mouse that made me lose 30-40% of games, damn thing... double-clicked every other click.)
