This works well if players want to skip the grind and get straight to the new campaign or to solo old raids.
The second heroic class released was the Demon Hunter, which begins at level 8 as well, and is connected to Legion, which is a great campaign to begin with. The last heroic class is Dracthyr Evoker, which begins at level 58, meaning players will only have to level up twice to be able to begin the Dragonflight campaign. This works well if players want to skip the grind and get straight to the new campaign or to solo old raids.
