First aid, fishing and cooking are all life skills that can be learned.
10 can only choose two subjects, namely tanning, tailoring, forging, jewelry, alchemy, engineering, peeling, mining, weeding and enchantment. I recommend jewelry or enchantment, but both are very expensive to practice, and the project pk is useful. Moreover, the current version has a helmet that is excellent and needs engineering to do and use.
Jewelry can be made into gems/ornaments that can only be used by oneself, and the promotion is not great. There are also rings that can only enchant themselves, and the promotion is not great.
Jewelry needs the support of a large number of mines, usually in cooperation with mines. Of course, some of them were washed after 70 years old and bought with money. The enchantment is better in this respect, and no extra skills are needed. Instead, the tailor can support the boundary.
Because World of Warcraft is about to release a new information piece, then all major majors will have new things to do, so it is impossible to predict the future changes.
I hope it will be useful for your choice.
