Very smart comment, for a kid. And then get M3, M4, M5... I don't want grouping battles based on Rank or equipment, I say the issue is to get balanced battles with balanced teams. Even today, I saw many battles with 6 vs 1 (or equivalent) for more than 15 minutes because some tanks can kill everybody with one shot, and of course, the opponents had left ! It would be better to know the power of a team before entering the battle !

Maybe one day you'll understand that it's not a rank issue but a tank level issue ! You can have high rank and fighting with tank M1 ! Battles should be automatically balanced based on the total power of the team ! I know : it's possible but so much job !
