Frontline feels impossible to win

Constalation, on Jun 17 2019 - 19:20, said: My line up is Caernaveron AX, ChristlerK (rental, 15games remaining I think), and the rental russian tank.  Right off the bat, every single match there is a guy who can hit the ammo rack on all three regardless of how fast they/I am moving.  Ammo rack on pretty much every single hit I take.  Even from the front, somehow they hit the ammorack.  So thats all my DPM, my HP all gone from some aimhacks or whathaveyou with 400~900 damage right in the ammorack.   Then there is the fact that defending doesn't give any credits or XP because you aren't capturing, holding a flank screws you over because you aren't hitting the people capping, no you are protecting their flank so they can farm and your reward is nothing.  And the second you just abandon the flank and leave the farmer to their fate, just so at the very least I get some form of reward, boom, deleted and all those tanks farming behind you die right after.

The only T7 I have is the Italian medium, and I need 3mil to buy a KV3, so no I do not have other T8 options to take. 

Every single frontline match I am ~sergeant and hit captain just once.  What gives, or should I give up?(Considering my line up is pretty terrible)  FYI my stats are terrible and I hit 2000 matches last week.
