Let's evaluate why this doesn't happen nor should it. If Pyros released alongside Alphascape with an ilvl 395 weapon and i390 gear

- Suzaku and 4.5 Primal are useless outside mount farming
- Crafted gear markets crash obscenely fast
- Alphascape Normal is obsolete
- Tome weapons are more or less useless
- 24 man gear serves no purpose as a "catch up" drop

In one fell swoop, almost every other avenue of gear progression dies. Even if the relic armor remained i380, that still impacts crafters since it's 100% better. Such a change relies almost entirely on the grind being tediously long and/or poorly designed ala Pagos. Basically, it needs to be so bad people don't want to do it.

And this side steps the actual reason raid weapons are superior. It requires skill. Savage may take less hours overall, but it requires your brain and a considerable amount of corporation from all eight participates. What does Eureka require? A pulse. And even that's debatable...
