The queue is there so that the game lets people in at a pace that doesn't destroy the servers if a bunch of people log in at the same time. Unless it is at like 3 am, you're going to be in a queue for like 30s usually all the time. It's not because of the bots.

Also, the bots will be banned in the next ban wave. If you are having problems completing a quest in a particular area because of bots, you have the option to go to a different world and can complete the quest there.
