PBS is shortly competitive multiplayer PvP game. 

Singleplayer is very short and is only there to unlock stuffs used for your multiplayer excellence (Personally It would be better just to delete singleplayer game from my perspective xD)

So the way to enjoy PBS is just doing lots of competitive multiplayer, with your character well dressed with lots of outfits and weapon skins 
To be competitive player, you will need to unlock all card packs.
