Server queues and instanced starting zones were something that seemed to relieve starter zone crowding (I didn't find the beta bad in terms of crowding, even on the weekend beta).
I was going to power level to 50, the leveling race in MMOs is pretty fun, the EGA has really removed the incentive for me and with that some of the fun - not sleeping for a couple of days to get to 50 isn't something I'm going to do when people are 20+ levels ahead of me from the start. Competition is where I find the fun in an MMO, this has been affected for me, hence my complaints.
