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?
