Mad 12000+ 4PC Player doesn't know basic 4PC game theory

This was in a FFA game just earlier today.  Due to an early castle towards my active side, I decided to start attacking green. When red decided to start attacking green as well later on, green lost his entire mind and threw a literal tantrum calling us teamers, not understanding the basic concept of 4PC that it's easier to attack someone who is currently under siege XD. This guy has played 12000+ games and doesn't yet understand the basic game theory of 4PC

(idk how to embed 4PC games so just have a link to witness the fun in chat )

Update: I was curious and checked the archive to view his past 4PC games, and found that an overwhelming amount of his wins are only when playing FFA including 1600s and 1500s, a good 500 points under him. And many times when he loses, he is quick to accuse everyone of teaming and calls them losers

Adding some more examples for fun so I can find later for entertainment :3

Finally, here's an example of joe being an entire hypocrite, doing exactly the same thing he gets so mad about and calls everyone "teamers" and "losers" for, in order to secure the 1st place win.
