I’m wondering if it is necessary that I spend the gold to buy the mount upgrade ability every time I make the leveling milestone on every character I level. For instance, my Warlock has bought every flight speed upgrade (not all path-finding achievements though), yet on every other character I have to buy it once more.
I’ve seen people level to 60 in instances and gain the achievement “Into the Wild Blue Yonder”, the achievement for being able to ride flying mounts, instantly.
Thanks!
