It's not so difficult, you just need patience.
Also I wanted to link to this guide for leveling hunters, even though it's for much higher levels than you're at and if you've got time spare to check it out, you could find valuable pieces of info about the concepts of class and perhaps try and adapt it to your own levels. At the very minimum, you'll get some insight into WOW Classic TBC Gold how the game plays at higher levels if you skim through the guide after the introduction.
It's not so difficult, you just need patience. Unless playing specific classes/builds, it's only possible to pull a single mob at the time precisely from the range and in a secure spot in which you're not likely to hurt anyone else. You also need to be sure to utilize every tool that are available to your class (or by using things such as first aid) to ensure you have 100% HP/Mana before pulling every single mob, in the event that you pull another one and it causes death. Yes, killing one mob takes a couple of minutes of mostly afking and auto attacking, as there aren't any resources usually available for other things, but I guess that's the reason some people enjoy it. The game is extremely slow.
Some will be apprehensive, but the boost is amazing when you are weak, starting with most capabilities and abilities to gain outplay potential has was a huge help to me. My first great toon was a warlock that I got to 30+ and gave up because I couldn't take how weak I was drinking heavily every pull. A booster for prepatch gave me completely different experiences. When I have a good build I'm not required to be slowed down and I can pull mobs without worrying about dying.
You appear to be trying to kill things at your level, or slightly higher. It is not necessary to spend all of your mana and resources in order to kill a single thing unless this was the situation. You'll find it easier to travel to places where the mobs are only a one or two levels lower than the level you are at. At first, it may be difficult to locate places that have enough quests, so you may have to straight up grind on mobs that are green without any quests until you are at the level you want to be at for the next zone. If the location you're questing in is always a couple of levels behind, then the area you are in will give you an simpler time.
There was one dominant EU horde guild , however in the list of boss targets killed first in vanilla, it's similar to... 7 horde vs 40 alliance world-first kills. It wasn't even close for someone who was part of a world-first-pushed guild. Obviously...great players were still able to make it on the horde team in vanilla but it was much easier for alliance, especially beforePeople in vanilla were completely ignorant of any aspect, especially until the buy WOW TBC Classic Gold very beginning. Are you certain that most players only made their racial preferences? This is absurd.
