No, this is a crappy way to play and I'm sorry this happened to you.
4 hours of game play and this happens!!!
Unfortunately, the only thing you can do is blacklist https://www.warlight.net/Profile?p=3784029060
and ask the rest of the community to blacklist him. I just did btw. With enough blacklists, he won't be able to play many games.

Don't let this discourage you mate. Keep on playing. WL is an awesome game!
