While this will be a welcome change as the player base gets smaller and smaller it still does not fix the central problems around crafting and the fact that no one is really buying anything. Increasing the cap may push the economy a little bit for those who just want 2 crafts at 100 but it won't do much beside raise the price of synth mats for a while - so in that regard you may have nothing to worry about.

If you want to revive crafting add some worthwhile non-synergy gear, even cursed/abj that will be applicable to the eventual 99 cap.
