If I'm buying it I'm going on opening day. I don't know what time of day you were playing (I never did see you on after that one night) but I've had no real issues with lag since they implemented the queue system. Yes, I have seen a few cases of loot/quest lag but nothing major.
I checked in on CST 5 from time to time but no one ever seemed to be around, so I'v been on EST 3 continuing to power level my hunter (lvl 35 atm), and checking out the mid and higher level content to have a better idea of how to play during retail. I guess I'll go on opening day as well, but I'm thinking it's going to be a nightmare. Before anyone gets going on his character, lets make sure we have the right server picked from the outset.
