Playing 1v4 against a cheating AI is the epitome of punching a brick wall. The game is fun versus humans because the game puts you at an even level, only your skill matters. How the hell can you compare the two at all? Additionally, the expert AI may be cheating, but it is not that great in a 1v1. Easily beatable.
In this case it's also about abusing skills and having RNG (luck) and on your side as well, ghosting, using broken doctrines or something that hasn't been balanced/fixed correctly.
