Where did you play DAoC because the EU launch on Feb 15 2002 in the UK was very smooth. There were issues with the Shrouded Isle EP launch though but without any shadow of a doubt beta testing and playing pretty much every MMO there's been since EQ, the worst launch for a vanilla game was WoW.
Servers down, crashing, lag, characters stuck looting, simply too many people in one place etc. On Turalyon we ended up with four days free time from the launch because it was that bad.
