If you missed the reputation grind with Soridormi in World of Warcraft Dragonflight Patch 10.1.5, you can catch up by completing Time Rifts
Time Rift Events – The easiest way to farm them! – Patch 10.1.5 Guide
As long as you do Time Rifts whenever you can (at least once a week, if not more), you'll build up a steady reputation with Soridormi. We recommend doing at least one Time Rift per day if you want your Soridormi reputation to be maxed out by the end of Dragonflight. If you want to get the "A World Awoken" meta-achievement for the Dragonflight expansion before we move on to The War Within, you should make Time Rifts a priority, especially if you're behind on your Soridormi reputation.
Luckily for WoW players, Time Rifts are quite common and can be easily farmed to gain effective experience.
Time Rifts start every hour at the top of the hour. When a new hour begins, a Time Rift event starts next to it.
