it was.... lvl 40 in TBC for the 1st mount, 60 the 2nd one (and 600 g), 70 the normal flying mount cost 800 g and the flying epic 5k g for riding + 100 to 200 g the mount :)
as an alchemyst on retail it took me 15 days from scratch to 5200g and get the mount to have the Netherwing drake chain quest availableQuote:
Wonder if this time it will still cost half your life to save the 5000 gold for an epic flying mount.
