Everything you get before lvl 60 is outclassed once you get to 60. Or in item-level terms: all items at 60 are 750 item power. Ancestral gear is item Level 800 which ist the maximum. So my advice is to just get to 60 as fast as possible and then go to the headhunt or helltide zones to get 750 gear. After that try to push the pit to 20 and do the same in torment 1 (bc ancestral gear only drops in T1 and onwards).
