Given you can already spend a FP to reroll a bad roll (the primary time rerolling is particularly powerful), this seems neat but maybe over-costed? Then again, "Spend a FP to roll twice and use the better" sounds pretty decent, so maybe it's just a framing thing. Perception is weird.
On the other hand, given earlier discussions of the tweaks to the FP system meaning that we burn through FP faster than Fate's system assumes we would, writing new things that use FP might be awkward on a more meta level (as opposed to straight balance).
Also, unrelatedly, many thanks for the well wishes and congratulations
. You folks are awesome.
