GW2 is the only one I remember that didn't have a single issue. And even then their AH was down for the first week, they had major issues with the over flow servers and guesting wasn't in until way later.
Rift had issues on early release, TSW did not, i think that's it for the last 5 years? I remember swtor having issues as well, 5hr + queues, characters stuck in zones, and issues for the early access. They even staggered the EA and still had issues.
I mean, obviously this could have been done better, but besides having more servers, which is just as bad, you are always going to have issues.
