Except for?? Several servers had overload issues in The Old Republic's launch, didn't they?
I started to play the game the earliest of the staggered release allowed, never once did I have a "wait in line" popup that lasted more than 10-20 minutes in the first week of the game launch. Compared to WoW multi-weeks issues. FFXIV RR multi-months issues or GW2 login server being DOS which stopped you from login in at all, SWTOR was an uneventful launch outside of a few servers being full.
