The queues are due to the servers being literally full. The log in bottle neck isn't the issue. Read the post - 100 people get let in after 100 people disconnect from the server. A lot of this server space if taken up by players logging in first thing in the morning, and AFK botting all day so they skip the queue when they get home from work.
