Sadly, most companies keep the beta running, actively scan and fix bugs, and then implement them on a consistent basis while checking out other critical components.
Little things, like server stability, load capacity, tester bug finds, balance issues, performance issues. . . . .
Like everyone else, I really enjoyed what little time I got in the beta. I was pleasantly surprised I got a beta key for being an ex XIV customer, digusted by SE account management [typical for SE] and shocked that their idea of trying to win me back was several "weekends" of beta play.
I'm married with Children. My weekends are not my own.
SE: you need to fix that if you wanna bring your disgruntled ex customers into the fold! I feel it's extremely fair for you to bend over backwards to please each and every one of your disgruntled customers. . . after all, we experienced 1.0, and that's X amount of our lives we'll never get back!
