It seems the idea of Core version vs Centus/Corpus ones was to be more cap-friendly (400GJ vs 450GJ) for the expense repping power (1288 vs 1449).
But the problem is no one in a sane mind would use it on a BS chassis (=choice core vs centus or corpus)! Because the BS has relatively big CAPACITOR, so this benefit could easily be ignored.
However.
We have beautiful case with GIST vs PITH shield x-large boosters!
While gist version has significantly less repping power (739 vs924) it also comes with almost TWICE less capacitor usage (400GJ 204GJ) which makes is â„–1 choice for top-notch meme cruiser hulls (legendary T3/Recon ships unkillable and or Curse!)
So, how about we tweak these CORE repairers in a similar manner? Yes, large ones cannot be fitted into cruiser hulls, but they can be used in a semi cap-stable battleship fits, thus, removing the necessity to fit additional rigs/modules for CAP-REGEN!
TLDR:
Decrease capacitor usage of Core X-Type Large Armor Repairer from 400GJ to ~225-250GJ (because core generally sucks!)
