Never had the time or consistency (or, to be honest, the inclination) to play clan wars. The gold ammo would just make it boring as every shot would penetrate no matter where you aimed or how you were angled.
I am utterly in love with the ELC AMX at the moment. Game starts, tear off and find a bush somewhere for a few minutes' passive spotting, then head back to friendly lines and find where the enemy have left their lines open; then dive through, murder their arty, and head back to troll the hell out of heavy tanks who don't have the gun depression to hit you when you're hugging their sides.
