Time-tested idioms are always right, there is really no free lunch in this world. It applies to war thunder here. Quest 1 is to reach account lvl 9 within 10 days, and I did it within 25 hours of grinding day after day with the help of premium account. Thereafter, quest 2 is to reach account 11 within 6 days plus the amount of time remaining after when you completed quest 1. This is where my jaw literally dropped on the ground. I barely made it with quest 1, and now the difficulty of quest 2 literally tripled! Double the amount of EXP required and 3/5 of the time is just ridiculous.
