The first iteration of EA, those points were much rarer. However, due to complaining about RNG fails (as almost all Larian changes have been spawned from dice and RNG complaints), Larian put in excess Inspiration Points for re-rolls.
I would like those points to be very rare and for difficult quest lines. Between loaded dice and these points, it is now almost impossible not to get the result you want. And yes, I know that is the goal of Larian in the first place.
They want to have 5e and the illusion of dice but give you 4395340540 ways to circumvent and manipulate it so that, essentially, the presence of a dice mechanic is irrelevant.
+1 for inspiration being a rare reward for difficult quest lines or optional encounters. Idk exactly how many we current get in EA, but 2-4 seems like a reasonable amount for EA. Maybe 1-2 that most everyone gets from the main quests and then another 1-2 that are rare and only ~half or less of players get?
