@ChugKendallOh i have been playing a lot of singleplayer games myself, and it has been enjoying for the most part even tough story isn't always the best.
I can completely understand how that would ruin it for you and it's never fun playing with toxic, offensive or players using slurs. There has actually been a few times i had to hide chat in game but that is pretty rare here in my experience at least.
Good thing in this game you will be able to play alone with bots as far as i know. Which is one of the things i am really happy they added back to Battlefield and i am looking forward to it. Great for practice and if you want to enjoy a game by yourself or not having to worry about really good players constantly killing you, making it harder for you to learn the game. Previous titles DICE has made like Battlefront 2015 the bots have been really well made and fun to play with in my opinion, hopefully they will be equally fun in this game as well.
