Yes, a whole phase of development will be beta testing. The thing is, the idea for most people of beta testing is playing through it once and noting some nitpicks. Granted, a lot of team members do this because they have other jobs to fulfill (like mapping) and they can't spare the time. But having an actual "beta tester" position means playing each new patch through and through, nitpicking obsessively and taking a keen interest in the challenge curve. Lot of people aren't up to the task, so we might have to find someone to help our current dedicated guy.
