If you want to buy an 80-dollar flying mount, just buy a biped dragon directly from Orgrimmar and Dalaran.

Secondly, heroic evolution is Stansom's time-limited dragon.

Then there is the Black Dragon/Twilight Dragon that Obsidian Sanctuary will play in 3+ 1 mode.

Other flying mounts are either prestige worship, team achievement reward or rare copy of BOSS, which is too slow for you.

There is also the most special one, which is professionally produced by players.

Beaded agate leopard and gold-refined sandstone baby dragon.

These two are game coins. Buy directly from the player.

Or the landlord can use Battle.net points to buy guardian giant Long Zhixin or Xingju from Battle.net Mall.
