End game NMs and Breath attacks

Seems like many end game NMs now are given significant damage resistance vs Breath damage. For jobs like DRG and BLU this is a problem for their damage compared to jobs that don't rely on these kinds of damage.

For example, someone posted a parse result of Wyvern damage during six Hall of Mul fights.
His Wyvern in 6 fights dealt 22,000 damage which accounted for 0.46% of total damage. He utilized Spirit Link with Empathy fully every 90 seconds to copy Phantom Rolls and Bard songs to his Wyvern and his Wyvern was kept near full HP the whole time.

Wyvern Breath was used 252 times and the average breath damage ranged from 16.17-22.83 depending on which element. No reason why DRG's pet damage should be so low, 16-23 damage?

Blue Magic isn't much better, heat breaths and thunder breaths with loads of magic accuracy do less than 200 damage with proper HP boosting gear and breath damage potency. Why are breath attacks so ineffective in endgame when it could help these jobs which already lack strong damage potential in these kinds of fights?

Because breath attacks are generally inefficient against many high level enemies anyways?

The Dragoon wyvern does low damage against high level enemies. This is nothing new. Breath resistance is far, far, far from the main reason for this. Any enemy with vaguely decent magic evasion will consistently resist most of the breath damage. It also has very little impact on the Dragoon's total damage output. Under ideal conditions, wyvern breath attacks never make up a huge part of the Dragoon's total damage because wyvern auto-attack damage is more significant in any condition short of spamming weapon skills so fast that the wyvern never auto-attacks.

Breath attacks are never the best damage spells in the Blue Mage arsenal. The only reason anyone should ever build around them is against enemies where their defenses and resistances are exactly setup in such a way that they are the best damage spells in their arsenal. If they aren't, then they should be using something else. Under ideal conditions, Heat Breath and Thunder Breath both have low potential damage, a high MP costs, long casting times, and long recast times. Under normal conditions, they do pitiful damage, but have a ludicrously long casting time, a ridiculous MP cost, and, to add insult to injury, an extremely long recast time. Most of the better damage spells could be more mostly resisted and still outdamage every breath spell in the Blue Mage arsenal.

Well, at least you two agree on the facts?
