There has never been a numbers-based analysis to support this patch decision. Nobody has ever shown numerically that storing is superior to up/front sooner gains on earlier SP.
Which makes this particular patch decision COMPLETELY RIDICULOUS. Why not just randomly change other balance features while the UI still doesn't work? Come on, it'll be FUN?!
I agree that there has never been a numbers-based analysis. That being said it is still possible to store policies by selecting it in advanced game options. No need to get upset over nothing.
