Until you get into level 60 gear you’re mainly going to want gear with as much stamina and armor as possible. It’s going to be best for you to have leather greens with “Of Stamina” > “Of the Monkey” >= “Of the Bear” > “Of the tiger”.
Along the way there are certain pieces like rings or weapons that give armor, these are very valuable for bear and a lot of the endgame +armor items are bis for bear
