They don't count as Blue Magic refers to a specific set of abilities that have been fairly consistent through out the final fantasy series. It's not primal energy that summoners use or dragoon abilities. I believe you know this but are being intellectually dishonest by creating a false equivalency with fin fantasy's blue magic and just any old ability used by mobs or bosses.

jfc... Okay let's make a very clear understanding of what Blue Magic or similar arts entail. You are not just drawing power from an enemy. It goes deeper than that. Blue Magic,Copy Magic, Pictomancy is utilizing a very high level magic to systematically replicate an enemies move and reconstruct it to allow use by an individual who would not readily have the limbs, mechanisms, or body structure to perform such maneuvers. This is done through taking on the said moves, and why not all moves can be replicated. Your body remembers the move, the pain or function, and the magic draws from that. This is why in XI it was established how dangerous this art was. You turn yourself into a living weapon, every part of your body a point to channel the magic.

DRGs merely feed off the eye of a dragon for power which stimulates their bodies, giving them enhanced skills. Likewise does SMN use Ahk Morn specifically? NO. It uses a very weaker form constructed by their art. And that aside, you are channeling, much like DRG, to perform this feat. SAMN in essence is a channeler, even Death Flare uses the still lingering essence of Bahamut to perform it. You as yourself don't have the full power to perform it at will.

Because those aren't Blue Mage situations in the slightest.

A Blue Mage learns the powers of their enemies, but uses their own power to recreate them. As you've pointed out, Dragoons/Summoners are using power -directly- from other sources to perform their arts. Maybe I'm wrong and Blue Mages keep eyes and ears of enemies and use them up to use skills in some kind of spell-reagent fashion. Somehow, I don't think they do. At least, I cannot see them doing so in FFXIV.

I was being facetious. Using it in the loosest definition. Blue Magic is iconic to the series with recurring abilities, which a handful of them already exist in game. Here are a few examples:

Mighty Guard exists in game as the tank's LB2 limit break. (I forgot about this thank you Valkyrie_Lenneth)
Aero and Stone have traditionally been blue magic abilities, though they have been relegated to CNJ/WHM.
Shadow Flare was an enemy skill in FF7, now it's an ACN/SMN/SCH skill.
Flash was an enemy skill (Jive) in FF4: After years, and is now a GLD/PLD skill
Freeze was blue magic in Final Fantasy 9. (Which interestingly enough, was a CNJ ability at level 44 in 1.0, then was given to BLM which retains it to this day.)

So there you have it, "blue magic" that exists in the game currently.
