During chain libs can be quite nice, alleviating some over-pop. But on the flip side, once chained down - all other mods from libs are usually a waste. Econ is too tanked for the income+BE sci to make a difference. WPA and TPA raw figures and native sci boosts are usually high enough that the lib mods to sci would have little effect. Your off is higher than what you can utilise and ME sci won't matter. Acre swaps will have diminished your libs to near nothing, possibly making other buildings that would have prevented the quick swap (rax, hosps, gs or even wts that could have prevented some of that NS and lowered the number of incoming hits during chain). Etc.
Libs can give impressive mods, but the volatile and dynamic nature of war makes them better at more stable provinces (TMs, and turtlers) than low-def hitters. I've ran Sage hybrid cores. And even with such a setup I was quite conservative on the use of Libs...
