I feel that the levelling let's focus on this aspect is slow

The levelling process is sluggish. It's true that WOW TBC Classic Gold it was designed that way, but I don't like it. It is not as smooth as it could be for the Hunter class with high DPS. I'm lacking mana, damage, and gold. Because of my tiny mana reserve, I am unable to take down every mob. Once I've killed a mob, I must stop to regain my health and mana. There are only a few feasible techniques that can allow me to be able to survive and also deal with damage. This will probably be improved in the near future, but I'm starting to doubt whether I can stick with Wow for long enough.

I feel that the levelling let's focus on this aspect is slow. I'm not denying that it's been designed that way, but I just don't like the texture of it. I am playing as an Hunter and I'm guessing that the levelling process isn't as good as it could have been for a class that has amazing DPS in the future. I'm lacking mana, gold and damage. Due to my limited mana reserve, I am unable to kill every mob. So once I kill the mob, I must end and regain health and mana. I have only a couple of viable skills that allow me to survive and take on damage, probably this will improve later on, but I am starting to wonder if I'm not going to stick with the game for long enough.

Ah, I didn't know you're only 22. The issue of getting enough quests should not be an issue If you know where to search. The add-on Questie is something I hesitate to recommend. It doesn't offer the most immersive experience, but it could help you get familiar with the game. If you're not interested in doing that, you are able to download Questie. It will show you many of the quests available. However, you may have to consult an online guide to help you determine the right level zone.

It's the last point, it's just the way it is. There is a limit to cheap TBC Classic Gold pulling one or two at a time dependent on the class you're playing. If you're not careful, you might die. Classic is a game in which you cannot just stomp on regular mobs in your level unless you have a max level character is able to funnel resources to your alt.
