Recommended for hunters.

For solo brushing, hunters and blood DK are generally recommended. To be honest, the hunter is still stronger when single-playing. There are some bugs in the long-range, and there are babies who can resist without fear of blood loss, and the output is much higher than that of DK. The blood DK is hard, but its so-called single-player brushing is to be honest, it is just a rogue, relying on the spirit to restore the blood and slowly grind the boss to death. It has no technical content at all. Just chop it with one knife, which is laborious and a waste of time.

It is very difficult for other professions, and maybe Shadow Priest can do it, but for this kind of thing, either you have a BB to help resist damage, or you are very tough and the BOSS can’t kill you. Other professions do not have babies that are resistant to damage, and professions that can be hit and gain bonuses are not like the blood DK, which can restore blood with just one hit. You can't add blood when you fight, and you can't output blood after adding blood, so it's very painful to single-play other professions.
