Never seen a MMO launched this badly, not even Diablo III was this bad, I didn't play SWTOR or Rift, but GW2 was flawless, some rare server crash but you could log back in after 30 min/max and then play for hours whitout problems.
Also keep in mind the GW2 had (and still have) MUCH more concurrent users logging in at the same time.
The only problem it had was the TP down for a week, but you could play it, any time, any day, 0 maintenance ecc.
So no excuses, this is not how MMO launch usually, this is 10x worse then anything I've ever seen, not even the 1.0 was this bad.
They should have fix this crap 8 days ago, then we could call it a bad launch like many other mmo.
