Yeah heirlooms are pretty terrible early in the expansion, and I’m not sure if it’s worth using them or not. The first quest of the expansion rewards a 280 azerite piece, or you can keep 10% exp and wear a heirloom ilvl 170 at 110 that jumps to like 210 after you hot 111. Probably best thing to do would be wear the 280 piece then switch to heirlooms for quest turn in
