So per Russ/PGI, HBK-GI quirk is changing from UAC5 to Gauss. There aren't many GI Gauss builds on this forum, and none so far that I can see that combine Gauss+MPL to maximize quirks. If you want to use both Gauss + 3 MPLs (sort of the standard HBK main weapon +3 builds), you're stuck with either a microscopic STD engine, or a passable XL engine. Here from stock I've loaded 40 Gauss rounds, kept the stock armor levels, added an MPL to the head, stripped both DHS from the arms, moved the Gauss rounds to the legs, obviously stripped out all the missile junk, and given it an XL245. Alternatives? Change the head laser back to something smaller and strip some armor off to get a standard engine in there that doesn't make you a sitting duck? Strip out one of the lasers entirely and try to keep as much armor as possible? I'm open to any suggestions. For the record, I still think this is a bad quirk combination. The Gauss is not a great close-range weapon compared to common alternatives like the AC/20, but the MPL isn't a long range weapon. An XL on a HBK is really only good for distance fighting but if you stay at range then you're wasting all the firepower of your MPLs. I almost like this GI build better for range fighting, like an HBK PPC Cicada. I'd *much rather* see the GI with an AC/20 quirk (before everyone raises the most-frequent objection that the G has the AC/20 quirk I'll remind you that 2 different Centurion chassis have AC/20 quirks) or, in lieu of that, an AC/10 quirk that might pair better with MPLs than AC/20 (fewer compromises on armor/engine). So, in advance of HBK-GI quirks switching from UAC5s to Gauss I thought I'd get this discussion rolling.
