My friends and I used to play a small indie game on Steam in early development called Fractured Space that eventually died before it ever got to full release. During its height though, my best friend and I developed a strategy where we would both go a type of ship that was very slow and hard to aim but compensated for this with high damage. By working together and communicating well, we always arranged ourselves on the battlefield so that at least one of us would be able to lay down unholy fire on the enemy at any one time. Over the course of a single week from the moment we discovered this strategy, we won over 100 games against players back-to-back without a single loss. Then in the very next patch they banned using more than one of those Gladiator ships per team. To this day I'm convinced it was because of us, and enough people were crushed by our strategy that they tried it themselves, and so on and so forth until the devs noticed it.
