This essentially demands you to not have a subweapon of any form and shape, for a mere -2 FP reduction on Bard skills (which doesn't even work right now).
Could this -10% FP reduction be changed to just a flat -5 FP reduction?
Additionally, it would be very nice if this also passively increased the range of all Song skills by 3, alongside the new proposed FP costs reduction.
It can help a lot on Round 0 Auto-Tune situations where your allies are too far away to receive any benefits.
