Maybe it was better when people could suicide ?

Ectar:   People can still destroy their tanks if they choose.  If you're really the last tank alive and want to end the battle as you feel you can't do anything, simply drive towards the enemy tanks and let them shoot you.  Previous the "suicide" exploit was players (mainly arty) choosing to drown their tanks at the end of a battle to deny the enemy team a kill/exp and safe in the knowledge they wouldn't get a repair/crew death penalty.   The bottom line is you can either actively play the game and try to win, or mess about with no intention to win.  The 2nd option is simply messing things up for anyone left in the battle and if you're that type of player then it's time for you to chose another game or start to actively play and not camp in a bush in the far corner of a map all game.   We're not going to support people joining battles just to sit about and do nothing.  

Ectar:   Revealing an allied position is against our game rules and players get reported for this and get punished for this all the time.  Regardless of another player's behaviour it's not for his team mates to act as judge and jury.  If a player is breaking our rules then you report it and we deal with it.
