i think they need to add more rewards for the challenges because as we all can see that the players who cant participate in events from tankoins paid they will keep wait for the challenges to come with a nice rewards but tanki keeps the same rewards 2 augments and 2 paints and the last rewards we all know 100 tks and a skin and they keep adding skins like SHAFT LC depends also if your buying the battle pass so the normal challenges dont get anything to help upgrading your tank so at the end they play bored ways like CAMPING because they cant attack like the buyers and i have experienced it and tried the TRY HARD way and BEING A BUYER in the game its really diffirent and i didnt also see a DC skin in the challenges and that makes us very clear about there way on ( if you pay you get ) ihope you get my point and the devs look about it and find a way for these ways because the game is getting boring by the way and for the future
