I actually live flamethrowers! If you can believe that 4.8k kills ahemmmm
I run 2 squads of them now.
They are amazing at flushing out all those PPD/PPSH users out of their objectives. I rarely see them used still. And that is normal, the weapon requires the most skill to use in the entiere game.
I have been using flamethrowers in moscow since May. And at first i struggled, but i wanted to unlock them so badly they in my eyes were the final unlock.
So i kept using them, and here i am now, a flamethrower enjoyer and that wins the games of low level axis players.
Best close range weapon in my eyes.
