Can you play the game before entering the balance section again
And can you provide a playercard so that there is proof that you play the game (let alone play the game well enough) to comment on the state of balance?
The shell switching is fine, and honestly I prefer the feature as a USF player. It's not hard to reverse out of battle to switch shells and come back in after the switch, and the option to use HE shells allows me to shit on infantry even more than I would if I only had AP shells.
