Eh... I've seen solid argument psychometry is outright detrimental, heh. It
is broken, but more in the sense of largely being a waste of points

You kinda' touch on it yourself, there. It
does save (sometimes a lot of, to be fair) time and effort/money, but... that's all it does. Literally all it does, save you time. Anything it offers can ultimately be acquired by reverse engineering or buying stuff from merchants/finding crap on the ground, so you're basically spending fairly precious/limited starting mutation points just to do that, instead of doing, well. Anything that actually
does something.
Don't get me wrong, I like it a fair amount myself (and also fairly often just cheerfully cheat myself in more mutation points on character creation, heh), but that's mostly 'cause I'm pretty lazy -- I don't think the argument's
wrong, per se. You're spending those exceedingly limited non-random mutations on something that doesn't actually get you much but a relatively short leg up on stuff like chem cells or lead slugs.
