Tigerinuzuka - sorry to hear about your terrible experience. I completely agree with you - DoF came out a really crappy shape.
In our defense - it wasn`t us - the developer, who released the game, but the publisher 505 Games - they basically released unfinished alpha version of the game. And with sales - it again wasn`t us, but the publisher who got their hands on your hard earned money.
We have broken off with 505 Games following that disastrous release, and did all we can to fix the game after that, with 40+ patches - including the features you mentioned - PvP and CoOp. So I hope you can see that we are trying
