Hearthstone legend, which professional winning rate will be higher when playing the arena?

Occupations in the arena are divided into three levels from strong to weak. The first gear is thieves, paladins and wizards. Thief is the occupation with the highest winning rate among old drivers, but it is not suitable for novices. Paladins and wizards are more suitable for novices and are also very strong. The second gear is warlock, virtue and shaman. These occupations need better card selection and certain personal skills to play well. The third file is priests, hunters and soldiers, with a relatively low winning rate, which is also recognized as a relatively weak profession.
