For me the most frustrating is to have to babysit a 2-3 hrs queue, having to relog multiple 2002 errors only to get kicked to the back of the line which is now 2000 more people large (after multiple 2002 error in a row)...
Q for people that have been part of previous expansions, how long did it take for the queues to decrease in length from being in the multiple thousands, let say down to multiple hundreds?

I fear this may last many months at that rate...
