We need a way to experiment with focus tree skills i.e. de-level or completely unlearn skills and get spent focus back. Just to make it clear: Unairu Wisp costs about 800-900k focus points. That's 4 days of grinding for only one skill (not counting capacity allocation and prerequisites). Then it appears that this skill is nearly useless (because of manual "chameleon" wisp pickups). Now I have 4 days absolutely wasted.
Focus 2.0 is great in terms of variety of combos it offers, but skills are expensive as hell and without a way to redeem wasted focus back players will be quickly burned out
