If people leave because they like/dislike a game and can't discuss it like adults, that's on them.
To say that there's too much negativity around should be a reflection more so on EA's product than the posters.
As someone that's been around and talking about this game for a long time, it wasn't always this depressing. The online banter matches the game quite well. We're stuck constantly rehashing and debating the same old things, because EA constantly adds nothing of real value, while leaving glaring issues in the game.
I used to defend the franchise strongly, but even I've grown tired of the way EA has treated their product.
