Look, if you want to do this goofy shit, be my guest, but understand that you're defaulting from the discussion as a rational person. No one does this, not metafags, not casuals, not ironmanfags - NOBODY does this.
A booster investment that offers no functional/noticed advantage to an already strong unit can therefore be assumed to go to a unit who a) WOULD functionally benefit from it and b) who offers a strong return for the investment.
Incidentally this is why it's dumb to hold Spirit Dusts against units like Odin, fucking one else needs them, so it can be assumed that if he's in play, his actual mag stat is higher than his average.
