I've been waiting for this game for years now and not being able to play in the closed BETA sucks. I know it's just a week but look at your playerbase, there are not enough people playing in the first day, imagine day 2 or 3 when fewer and fewer players will play, you can't find bugs with only a hand of players.
Also I can agree with the stress test, if you want to know the limit of players that you can have in your game you won't find out until the game gets big and won't handle it but that's just my opinion. Just sad I didn't get the opportunity to help you and play my childhood game.
