Step 1: Introduction and Story setting

Step 2: Mild grind (Glowing weapon step)
Variant Dungeons
Normal Raids
Roulettes.

Step 3: Continued Storyline

Step 4: Mild Grind (Glowing weapon step)
Current XPAC fates, Normal Raids, Roulettes.

Step 5: Continued Questline, setup for the finale.
Normal Trial
Extreme Trial with alternate rewards.

Step 6: Finale (Complete Relic)
24 man raid, around the same difficulty as current alliance raids
Alternate Savage version like DRS with a unique mount reward


This way you get a comprehensive story, Renewed focus on older content from the expansion that does not see much play, and a normal and extreme trial and a 24 man alliance raid with savage alternative.

Now you have a relic that allows anyone to complete it, requires a small time investment in each, funnels players into content like Variant/Criterions and Normal Raids.

This not only speeds up queue times for content that casual players enjoy to run, but gives options for better players to do Extreme and Savage versions of each trial/raid.
