Installing a youkai without any base aptitude (which is most of them) will likely bring your aptitude down by 1-4 points, this can become a problem because Aptitude boosts your stats, and installing should boost your stats as well, but when your aptitude is brought down so are your stats.

What I'm mostly saying is I think that installing shouldn't change your aptitude, either that or give youkai 4 base aptitude to even it out.

Beyond the slight buff to installing, this would also be a huge relief in not having to calculate the aptitude changes when getting an install build together, a real nice quality of life thing, +1 and so on.
