Do you think implementing a AFK Kick outside of Expansion Releases would do anything?

The problem isn't really people AFKing, it's that SE deliberately set it up to lock down congested servers during peak times. This was to help speed up logging in to your home world during expansion launch and savage progression, but we're far past that and servers are nowhere close to maximum capacity.

As for why you get login queues now, it's because the servers are designed to log in batches of players at a time to help with server stress, it has nothing to do with congestion.
