Just from glancing the suggestions over, I did not see anyone mention adding a friend list.
It would be an awesome thing to have and it would help make way for other features, like private matches between friends, trading (like someone else suggested), and tons more.
others are welcome to add their ideas that could be added with a friend list.
I suggested that or something like that. Mostly what I said was it would be good to be able to send private message to other players, search them, be able to invite them to the guild with clicking on them (and then some easy button option on their profile for invite), not through invite in guild since its slow, you have to write down or remember a lot of codes and still a lot of codes bugs out and show not existing.
