A BLM proposal - Removing Sharpcast

[Lumadurin]

...and replacing it!
You know how Fire I has a fixed chance to proc Firestarter (free Fire III swiftcast)? And how Thundercloud (free swiftcast of Thunder that is also front-loaded with the total DoT potency) has a fixed chance to proc on each DoT tick?
What if instead, Fire I (and maybe Flare so that the AoE rotation follows the same rules) always generated a resource that could be spent on a guaranteed Thundercloud or Firestarter proc?
And say you could store up to maybe... two or three of these resources?

This would make BLM's movement/damaging capabilities more predictable and feed into the idea that the class becomes exponentially stronger once you learn the fight, while also granting it more flexibility in fights the user is less familiar with. You could either spend the resource on Thunder procs (at the appropriate point in your rotation) to boost your DPS, or you could spend the resource on Fire III casts if you get targeted by a mechanic mid-Astral Fire.
In a sense it'd be like lowering the skill floor but also raising the skill ceiling, since your snap-mobility is less dependent on getting good RNG.

This would also mean you no longer "waste" procs if you're unable to use them (multiple Thundercloud procs in rapid succession) or don't need them (Firestarter procs when you don't need the movement).
Although perhaps Fire III would then need to be unable to consume this resource in Umbral Ice so you can actually stockpile this resource.
