Even QM admitted Infernal Disease is too cheap, so it should be changed for final version of CBM [1.7 looks like beta, so there is hope for change, so we should make suggestions
].
And yeah, some items need price fixes [but that means lowering paths needed to forge them - it may be not so bad with more expensive boosters though]. It will be mostly 25 and 40 gem items, which were very expensive and rarely used even with 25% forge discount.
Would anyone now forge Stymphalan Wings, Bone Armor, Jade Mask, Armor of Invulnerability or even Gate Stone?
