Agreed, it becomes annoying sometimes depending on the situation.
I think they should completely remove this feature, it’s annoying and I don’t understand exactly why it’s there. Hear me out, one does not get that much friend requests. When your offline, you only get friend requests from your friends that you give your code or if people from past matches send you a request in the add new section in friends. Really you don’t get much, one usually either accepts or declines quickly when your online, it would be the players fault of having a pile of requests, except if for some reason you get swarmed with requests from previous games.
I would like to know if the developers have a different reason for friend requests disappearing. I don’t know of any other game that does this.
