Are both of the mounts rare or is it the only the flying one is considered rare or both? Or both are common drops?
All if then are rare drops. Orginally only the ground was.
pretty rare.
got the alysrazor one couple weeks ago thanks to the drop buff. takes longer to fly there than to farm that particular mount so you might as well do it.
glad i never have to go there again.
They are both rare, but to my knowledge the Ragnaros drop is more common, while the Flametalon appears to be bugged and attempts do not display properly on Rarity. I farmed far longer to get the Flametalon mount.
wowhead has all the information you would need about all the mounts
Both are rare. I got the pure blood fire hawk when content was still current and I just got the flame Talon ground mount during this event. However, if memory serves the ground mount is available in both normal and heroic where the flying mound is heroic only.
