It sounds like MyMagic+ might reduce the # of FPs used per day, at least till Disney convinces the 1% and later the wealthiest 5% to spend $$$$$ on incoming (?) unlimited FP ticket options.
(And what a fun opportunity that will be to explain capitalism to your young children in Fantasyland!)
But for now, instead of the tiered plan of one popular E ticket FP,
and 2 FPs for attractions you might not otherwise even visit,
how about just letting MyMagic+ users get any 2 FPs per day?
They could still keep the 3-tier option for guests who'd prefer 3 FPs.
