I agree with the opinions that panzer should not be enabled/allowed within a game that counts less than 10 players. I know the intention was to keep ETL2 the same as ETL1, but it seems a lot of objective based players are joining ETL2. If you've got a 4v4 game going on for example and an experienced players takes panzer, it might result in a 4v2 if the panzerplayer kills 2 players of the opposing team (which is realistic if someone experienced takes panzer and knows where to shoot). I know it's part of the game of course, but I still think enabling panzer with 10 players or more will do the game good (especially the more objective based ETL2 games).
Just for what it's worth
