Some of the players decided to fight in air battles only. There are multiple reasons: they are either so left behind the mighty tanks, so decided to start the new skill where they matter, or they are simply a member of a country's air MU.
The problem is ground fighters can still farm up to dozen TP medals a day since the requirements are not increasing, damage required stays 100 000 000. And many tanks do that multiple times a day, earning endless amounts of cash to buy weapons and high Q houses, which enables them to hit even more and earn more prestige points, greater energy recovery and more bars... it's a never-ending circle of gaining money and stats. And when they hit eppic battles, phew cmon.
And then they pay for packs in black market with CC.
And then there are boosters and rockets which air fighters cannot use.
Old players who started air fights have to make the same damage to get that medal, 100 000 000 in air battles, which is insane. A separete True Patriot medal should be introduced for air fighters to start from 100 000 (the same as with regular TP medals).
