I didn't believe they would make this kind of change but a significant amount of people were asking for exactly this, and crucially it's the easiest fix they could make. Yoshida has always had the belief that it's impossible to make heavy adjustments to old content because this hurts their ability to produce enough new content in a timely manner. I thought CM/Prae might be an exception, but no apparently they don't have the dev time to make these into solo instances with NPC allies who use squadron AI behavior or anything like that. If the solution isn't perfect, that's why, it would have delayed the patch or reduced the amount of new content in the patch.
