Yeah, making sure to document and take screencaps requires much more of my attention than normally playing. Of course with a turn based game, combat bugs would be easier to spot, I wouldn't be mashing buttons trying to stay alive and take a screencap.

The beta I was in 2 months ago was a lot of work, and it was a small one (about 60) that turned into a large one for one weekend (about 500) when they opened it up. They got a huge amount of feedback, and I imagine wading through reports has been a bit scary. It did help them decide on some things though.
This last one left me antsy, it seemed to elevate my inability to wait for the actual product. :P
