I work in software engineering. My QA person sets up QA tests. It is 42 different versions of poking at the software from every angle. He tests old features to make sure we didn’t break existing functionality. He test new features to make sure they work as advertised. He does things that “real users” would never do. If you were in beta would you ACTUALLY be a -good- beta tester… if not…why should blizz give you access? Especially NDA covered access.
Oh also, Blizz just announced that Blizzcon Tickets will be available for purchase on June 2 and June 5. Get your refresh buttons ready.
