Cant say I recall the issue you’re describing when im thinking back at my journey to 80.

Tho theres a tendency in modern mmorpgs that leveling is a breeze, in retail world of warcraft you can pull 20 mobs and blast em down. In classic world of warcraft you are often dead if you pull 2 mobs instead of one. This game is leaning slightly to the latter where you sometimes need abit of patience and thinking ahead before you pull camps or patrolls. But generally speaking like I said, I dont remember questing being a struggle at all.

I think you will be fine if u just keep going and maybe being more careful.
