I have two thieves, one is peeling herbs, and the other is jewelry+engineering.
Peeling increases the chance of crit by a small amount, which I think can be ignored. The key is that peeling is the first choice for small wealth at first. You can peel the skin first, and then wash it when you have some money or feel tired of peeling.
Of course, peeling+leather making is also a method, and leather making is to make money by making armor pieces. But most of the equipment depends on BOSS, so the significance of making leather is not great. After the new expansion, making leather will be of great significance, just like just opening TBC, WLK and CTM, and it will be very profitable. )
In fact, there are many thieves who study jewelry, because jewelry can provide three kinds of super-strong gems, and the attribute of gems is that you can have whatever you choose. It is the best of all attribute bonuses provided by various majors. But practicing jewelry costs money, 1-450 is about 6000G g, and it's a little tiring to make drawings every day, so you are a casual player. I don't know if this is suitable for you.
Let's talk about engineering Engineering has a strong advantage in PVP, especially in field PVP and battlefield. Rocket belts, parachutes and cloaks provide additional properties, but it takes about 6000G to practice engineering. But once 450 doesn't need to do task drawing every day, all skills can be learned directly. So it's easier. If you are willing to invest once, you can study engineering. And it will be more interesting to connect at 1-450.
If you are willing to invest. I recommend you to study engineering. For another skill, you should either mine, herbs or peels. I suggest you learn from me. Mine is more valuable than skin. And healthier, more meaningful than crit.
If you want pure leisure, then double mining, mining+skin digging.
