Which, iirc, put them at 5 ilvls behind the Twintania Allagan weapons. This made many of them the BIS weapon due to substats or close enough, that it made the playerbase have even less of a desire to beat Twintania.
If they make relics as strong as Savage, then there's no reason to do Savage, other than to unlock Ultimate, and if you're not doing Savage regularly enough to get some weapons, then you're not going to pick up on Ultimate as fast as you need to in order to clear it in 4~5 months.
More than that though, people wanted them to continue the relic questline. They wanted them to make them better than all raid and primal weapons, even if they had to upgrade them every few levels going into Heavensward. They didn't, and stated the reason being that they didn't want new weapons to feel pointless and they didn't want a repeat of what happened eventually in FFXI. This amounted to, "If you don't have your relic/mythic/empyrean/aeonic, then you can't join my PUG." They want every player to be able to take different routes and still do well. Relic is just another path, and it's damn good for how easy it is, especially now.
