Nightmare Mount Drop Rate higher on Ifrit-EX ?

[Rymm]

I will have to strongly disagree with you on that. Ifrit you still have to watch out, and stop DPS at certain points due to the nails auto-wipe point. Garuda, even if you drop her below the amount when the adds spawn, you can massacre her and only those that aren't level 70 in the unsynced group won't survive(tanks lower than 70 mostly survive too).

As a 70 PLD I completely ignore the first two nail phases and burn Ifrit. The only ones I bother to kill are on the last one because he will stay immune permanently while continuously spamming his aoe. It requires a little extra healing after each of the first two aoes, but it's not like I would be doing anything else right then as he is still immune for a few seconds. As for the hardest ex primal to solo now (aside from King Mog) for me it would either be Ramuh because the (relatively) lower tank dps on the adds coupled with all the running around and dodging lightning orbs (which he always seems to put right on top of the adds) makes him a pain in the behind, or possibly Titan because just standing around doing nothing during Goal absolutely kills me.

I've got all the primal ponies and both times I've seen the Nightmare drop, it has been from Ifrit. In fact, I saw both Nightmares from him before I saw Aithon. By doing the primals in a random order and skipping the ones once I got the pony from them- I dropped Boreas first (actually on my first Shiva run,) then Gullfaxi, then Markab, then Nightmare, then Xanthos, then a loooong stretch of nothing before I finally got Enbarr and Aithon.

I don't know if they changed the drop rates since ARR, but it was easy to keep track of as I was soloing primals to get the PLD lvl 50 8-man dungeon mount, but I got all 7 ponies in under fifty runs.
