If you have that many "friends" then you're going to be forced to ignore the majority or not really even know them that well.
If you want bigger groups of people just make a guild/guild alliance.
It doesn't hurt anybody to have this expansion, sure. But do we really need the ability to add everyone on the server to our friend list?
Personally I've held a group of around a dozen people close to me my whole life. It works out way better than surrounding myself with people I barely know.
