Prior to ATI's stagnation, the was a lot of development, and a lot of other work that was going to be incorporated into armory but never had the chance to due to ATI stopping development. Furthermore the was a lot more testing and higher quality assurance than right now. I'm sure you have noticed that goatpig's releases have many bugs that would have been caught if there were more testing.
For my defense, my first 2 solo versions came with a lot deep changes to the DB and a lot of new code, which increases the bug surface tremendously. Upcoming versions won't modify the DB anywhere as much.
