Primal Drops for Blue Mage

[MsQi]

Rng encounter unless a boss, rng on said enemy using it and rng they hit the right character you wanted to learn it so yes there was rng chance to learn just no rng after the skill was used on said character. 3 instances of rng vs 1 in ffxiv. ffxiv is incredibly low rng chance but at least its 1 roll vs 3

Those RNGs are just part of the battle system of the games involved, not something built into blue magic learning mechanics. (Some of those can be circumvented though use of other abilities.) That's like saying the mechanics of a boss fight represent a short coming in the blue magic learning mechanics.
