There's 700,000 beta registrants. It's around 5,000 people per server. They even had to take down character creator for a bit to ease congestion traffic going into the game. If the people (1.0 players included, just because you haven't got your key yet doesn't mean every 1.0 player is going through the same thing) who HAVE got their keys are still working their way into the game - they're NOT going to keep spamming waves of keys out until the ACTUAL BETA is stable and running for the people already playing.

The only thing that "isn't realistic" is the majority of the attitudes people have about the first 24hrs of a beta test. You're excited, we get it - I am pretty excited as well and I'm still not playing either but this "WOE IS ME CAN'T BELIEVE SE WORST TREATMENT EVER" is really pathetic.
