It's way more complex than you're both arguing. Not least because SWC is a thing. Investing in a BS13 2W ARM4 HMG is a great SWC investment compared to 2 BS12 ARM1 Sptifires. It's a matter of list composition and table design (tables with sparse DZs start making fewer, stronger pieces more viable) as much as points. There's a few things that do skew in favour of 'not HI' troops though: Mimetism is undercosted. Armour is overcosted. Hacking/EM vulnerability isn't costed in. Middling CC (14-16) is overcosted. More orders is the only solution to some problems (Xenotech anyone). I think overall the points system is pretty good: but it's reached the point where the bits where it less accurately reflects tabletop reality is increasingly obvious.
