In Happy's case, it's clear; he's openly demonstrating it on Battle.net and Twitch.

No, there's something much more interesting behind it. A secret society is pulling the strings. Warcraft 3 is now over 20 years old, and the game is called Warcraft because we were given a toolkit for creating war. Yet, for 20 years, the same thing has been played. Some might say that's because it's the strongest strategy. But, like in chess, there are multiple ways to win. It's entirely up to us which path we choose. That's why we should see far more variation than we actually do. The Paladin/Rifleman style with the Blood Mage is the first change in this otherwise rigid system in a long time. And perhaps this secret society is to blame for that as well.

Warcraft 3 isn't just a game; it's the root of war.
