The Whirlwind Axe quest becomes available at level 30, but realistically, you'll complete it around 34-40 unless you get help. Buying quest materials from WoW Classic 20th Anniversary Gold the auction house can save enormous time. Whirlwind Axe can easily carry you into the late 40s. After that, dungeon upgrades like Gatorbite Axe from Maraudon or high-quality blues and epics may replace it....
