It's downright pathetic and baffling that this feature hasn't been implemented. Do you know what I had to do in order to avoid awkward situations like this? When I first made my account, I literally told everyone of my friends that I'm not taking friend requests. Now, I did add a few, but even between the handful that I've added, I'm always getting requests from every which direction and friends begging me to play with them and not others, etc. As a result, I end up being the ****** for not dividing my only playtime between the people I know who play this game.
I wouldn't have to tell my friends to buzz off if this simple feature were added. I'd really like an explanation from Riot as to why it hasn't been done already! How long has this game been out?!
