The levelling process is slow. I can't deny it was designed that way however, I don't enjoy it. I am playing as a Hunter and WOW TBC Classic Gold I guess the way to level isn't quite as good as it could have been for a class with great DPS later on. I'm not getting enough mana damage, gold, and mana. I die all the times but I'm not able to kill one mob at a time because I am limited by my mana pool. When I've killed a mob, I must stop to restore my health and mana. I only have a handful of skills that could enable me to survive and deal damage, probably this will improve later on but I am beginning to question whether I'm not going to stick with WOW long enough

Oh I didn't realize you're just 22. There's a problem with not having enough quests to complete shouldn't be in the first place if you know where to search. I'm not sure if I should suggest the addon Questie since I'm not sure it's the best way to get into the game in the first attempt... My advice is to be sure to immerse your self in the quests and go slowly (read them , etc. ), but if you're not the kind of person who would like to do that, then download the addon known as Questie and it'll guide you through a number of quests that you can get, although it is possible that you will need to use some kind of online guide to finding the appropriate levels.

It is what it is. You are only able to take just one or two monsters at a time depending on your level. If you're not careful it could be fatal. Classic is a game where it is not possible to simply stomp on regular mobs at your level, unless the highest level character can funnel resources to your alt.

Questie is available for download. Download WowUp, an addon manager which will install your addons in the appropriate folder and notify you when updates are required.

Questie will reveal the location where the level-appropriate quests for your particular faction are all over the world. It will also show you where to find the minimap, map and quest objectives. As you start to progress to higher levels of play, travelling to the opposite continent or to other areas which aren't readily apparent become essential for the smoothest learning experience. I can guarantee you that there are quests that are appropriate for your level of play in the game, however, you might not be aware of where you are. Questie helps immensely with that.

It is also essential to choose the right weapon. If your weapon is levels behind, you're likely to be struggling to kill the appropriate level of mobs. Classic/TBC will always be difficult to take on several enemies simultaneously. This is the way it was created it makes the leveling process more buy WOW Classic Burning Crusade Gold fun overall, but can frustrate players who aren't in the best attitude.
