Ofc not you can even look to live, everytime somebody came across a technique like this one, Blizz would change it. Im talking about raid farming for WOW Classic TBC Gold gold, Blizz has nerfed this after nearly every expansion since they discovered that people were doing it. If this had been carried out back then, it would last like a week, not years.
I believe that the levelling, let's focus on this aspect it's slow, I don't deny that maybe it's just designed this way. I don't love the consistency of it. It isn't so smooth as it should be for a Hunter class that has a high DPS. I am lacking mana, gold, and damage. Due to my tiny mana reserve, I am unable to kill every mob. Once I have killed a mob I have to stop the killing to replenish my health and mana. There are only a handful of viable techniques that can allow me to survive and deal the damage. This will probably get better in the future however, I'm beginning to be skeptical about my ability to remain with Wow for a long time.
I'm thinking that the levelling we'll focus on this particular aspect it's slow, but I'm not going to deny that it's designed this way and I don't love the consistency of it. I'm playing as the Hunter and it seems that levels aren't as effective as it could be for a class with an awesome DPS in the future. I am lacking mana, gold, damage. Because of my low mana pool, I'm unable to take down every mob. Once I have defeated a mob, I must stop to restore my health and mana. There are a limited number of useful abilities that let me endure and take on buy TBC Classic Gold damage. This is likely to improve over time however I'm beginning to doubt my abilities to stick to Wow long enough.
