I wasn't able to be able to pull this many, and WOW Classic Burning Crusade Gold manage them as efficiently however I remember farming ZG trash using my mage and making decent gold taking a handful of packs at a time and doing it in the old-fashioned kiting method of blizzards.

You're not even able to see it live. Every time someone found an approach like this Blizz would then change the game. Im talking about raid farming to earn gold, Blizz has nerfed it following basically every expansion since they discovered that people were doing this. This would have been possible earlier in the day and not in the past.

The levelling is slow. I can't deny it was designed that way, but I don't like it. I'm playing as an Hunter and I think the levelling process isn't as good as it could have been for a class that has amazing DPS in the future. I'm not getting enough mana and damage as well as gold. I am constantly dying and can't take down every mob in the same way because of my small mana pool. So once I kill an enemy, I have to stop and regain mana and health. I'm only equipped with a couple of viable skills that let me survive and to deal with damage, probably this will improve later on, but I am starting to wonder if I'm not going to stick with Wow long enough

The levelling is slow. I can't deny it was designed that way however, I don't enjoy it. It's not as smooth as it should be for the Hunter class with a high DPS. I'm not getting enough mana damage, gold, and mana. I'm always dying and I am unable to kill one mob after another because I am limited by my limited mana pool. Once I've killed the mob, I must end and recover health and mana. I'm only equipped with a handful of viable skills that let me survive and to deal with damage, probably this will improve later on however I am beginning to think that I won't stick to Wow for long enough.

Ah, I didn't even know you're only 22. The problem of having enough quests to complete shouldn't be there if you are aware of where to search. I kind of hesitate to recommend the add-on Questie since I don't believe it's the best method to play the game for the first time... My advice is, try to immerse your self in the quests and be patient (read them etc. ), but if you're not the type of person who wants to do that then just install the addon dubbed Questie and it'll provide you with a variety of the quests you could complete, but you may still need to follow an online questing guide to find appropriate level zones.

Last point is, it's just the way it is. Based on the class you're playing, you're typically only able to pull one or two mobs prior to having food or buy WOW TBC Gold drinks or eat. Unless you're cautious, you'll end up dying at times, no matter what. Classic is a type of game where you can't just crush regular mobs in your level unless your max level character is able to funnel resources to your alternate.
