This game is having a hard time because of the flimsy multiplayer support system. the constant disconnects, and potentially extremely long match up times are literally killing this game.
When you get this fixed, and please only after you get this fixed you should at minimum allow players from the Xbox1/Ps4 to invite players from the pc to private games.
This will begin to draw players back to the game by showing them some real progress on cross platform multiplayer. This is one of your games largest attractive properties in my opinion.
This will generate a lot of positive publicity which can only help your sales.
Gamers everywhere have wanted the industry to take this step for a while and If you can manage to pull this off successfully it will be a huge deal.
You could be one of the leading companies in a new age with the opportunity this game gives you, please do'nt waste this chance
