Hey, you stole my line (see my sig). You're right, it seems like Firaxis has abandoned regression testing. They only seem to be piecemeal testing new stuff, ignoring the potential ripple effects of the changes. I think the silver lining here, though, is that most of the regressions have already been fixed in Bhruic's unofficial patch. If they botched a new feature---for example, Blitz for ships---then it would be a more complicated decision whether or not to address it in an unofficial patch. Would the fix preserve unaltered gameplay? What was the developer's intention---did they botch the code or did they change their minds and forget to update the changelist? With that kind of communication from Firaxis being unfortunately rare (with much-appreciated exceptions, such as when Alexman confirmed that barb spearmen and galleys were unintentionally left out of Warlords 2.08), we'd probably never know.
