Consolidating Stormblood gathering skills
In Stormblood, the devs have tried to consolidate skills, with direct upgrades of skills automatically replacing the old one (stone and thunder being examples). Why then does Impulsive appraisal II, Unearth III, and Bountiful Yield II not do the same? These are literally direct upgrades of Impulsive appraisal, Unearth II and Bountiful Yield, each with the exact same ability (though bountiful harvest is one/two/three instead of just one) and mana cost as their predecessor but adding the addition of "increase is determined by perception".
