Suggestion for new medals:

Lert: 'Scrapper': Do the most damage of your team in a victory, in a bottom tier medium or heavy (at least two tiers difference) and survive 'Patient'. Do the most damage of your team in a victory, in a bottom tier TD (at least two tiers difference) without taking damage in return 'Weightlifter'. Do the most damage on your team in a victory, in a bottom tier light tank (at least 3 tiers difference)   A few medals for good players to farm and medium-skilled players (like me) to strive for and bad players to complain about "waah they should be easier".
