You haven’t actually shown that.
X thing got buffed like this so Y can be buffed too doesn’t actually hold water.
Synth did actually need a buff particularly after the addition of the other boosters that also lacked side effects.
You just want to boost something in the hopes that it will become more valuable. And that may very well not be the case. Do to the high supply of these items compared to their current demand you will need to significantly increase the demand in order to see a significant increase in price.
