We all have 1001 ideas we would like to see here. Fizzer has said it so many times over and over again. USERVOICE IT!
Perverted by some players, it just your view of it. If rules allow it, there is nothing wrong with it. Neither is there nothing wrong if you attack your team-mates out of fun, revenge or what-ever reason. Make lottery or rigged games. Open-games will be of poor quality always. If you want to play by your rules - find friends, trusted players etc. Changing the surrender rule will not change the players quality, attitude or behavior in game.
So playing strategically in team-game is perverting, what else is new here? Or read rules before you join and please don´t whine after if you did not like them in first place, but still joined.
Or maybe this is exactly what Fizzer had in mind, this will be the new Warlight-changing update we all been waiting for: https://www.warlight.net/Forum/220634-update-318-coming-soon
