Download the addon Questie. Download WowUp an addon manager that will install your addons in WOW Classic TBC Gold the appropriate folder and notify you of updates that are needed.
Questie will reveal where your level required quests for your particular faction throughout all over the world. They will provide you with the exact location to go to complete the quests on your minimap and map. For smooth leveling, it becomes more important to travel across continents or other areas that aren't easily accessible. I can promise you that there are quests appropriate for your level in the game, even though you may not know about them you are. Questie is a great help with that.
It is also crucial to choose the proper weapon. If your weapon is levels below, you're going to have difficulty killing low-level mobs. However, facing more than one enemy at a time is always going to be a challenge in Classic/TBC. This is exactly how it was planned. While progressing in level is more fun, it can also frustrate players who do not have the right mindset.
The levelling process is slow. It's no doubt that it was designed that way, but I don't like it. It is an Hunter class, and the levelling isn't as great as it ought to be for a class with an extremely high DPS. I lack mana, gold, and damage. I'm always dying but I'm not able to kill one mob in succession due to my tiny mana pool. So once I kill an enemy, I have to stop in order to recover my health and mana. I have only a couple of viable skills to help me survive and deal injuries, and I'm sure that it will get better later on, but I am starting to doubt that maybe I won't stick to cheap TBC Classic Gold Wow long enough
