If you are one of those testers who entered so late in the process, then you, like myself, might be finding that despite your best efforts, the lag does tend to color your opinions and feedback about the various quests.
Personally, I try to add into the comments section that I might have rated the quest as more fun had I not died twice, failed to pick up the items faster than the characters with whom I was competing, or spent what felt like forty minutes trying to kill X number of mobs.
Nonetheless, while certain experiences seem so novel and interesting, others can drive players right back to the live realms because they get sick of investing so much time and effort into something that simply does not work with so much lag, or listening to the complaining and counter-insulting that goes on in the chat channels.
Are you stuck wishing you'd been able to enter the Beta when the population was more stable? Are you forging on, or have you mostly forgotten about your key and chosen to wait until release on November 13th? Were you an early tester who is now annoyed with the increase in lag and annoying behavior?
