I feel that the levelling let's look at this particular aspect is slow. I don't deny that maybe it's designed this way and I just don't like the texture of it. It is a Hunter class, and the levelling isn't as great as WOW TBC Classic Gold it could be for a class with an impressive DPS. I'm not getting enough mana, gold, and damage. Because of my small mana reserve, I am unable to take down every mob. Once I have defeated a mob, I have to stop in order to replenish my health and mana. There are only a handful feasible techniques that can allow me to survive and deal with damage. This will probably improve in the future, but I'm starting to doubt my ability to keep playing Wow long enough.
Oh I didn't realize you are just 22. The problem of not having enough quests to complete shouldn't be a problem If you know where to search. I'm not sure if I should recommend the addon Questie because I don't think it's the most effective way to experience the game on your first try... My advice is to get yourself in the quests , and do it slowly (read them , etc. ) If you're not the kind of person who likes to go through the process, then download the addon Questie and it'll show you a lot of quests that you can complete, but you might still have to follow an online questing guide to identify suitable levels.
Last point is, it just is what it is. It is only possible to pull one or two mobs at once according to your character. If you aren't careful and you're not careful, you'll die. Classic is a game that you cannot stomp even regular mobs that are your level until you've got an upper level character, and you are able to funnel resources to an alt.
Questie is available for download. It is possible to cheap WOW Classic TBC Gold download an addon manager (highly recommend WowUp) which will automatically install addons in the correct folder and notify you when they require updates.
