Nothing we've seen about Allag, and that the era Azys Lla was from in particular, makes me think they were ever even remotely kind or cared. They didn't conquer Meracydia because they thought they'd run it well/better than the people who were there, or even because it had resources, they conquered it because it was there and they hadn't conquered it yet. And then left it a blasted wasteland, because their only real objective was conquering it.
Does this trend actually continue until Endwalker? Because relic weapons stopped getting unique names with the Eurekan Weapons in Stormblood, with the brief and short-lived exception of the first-tier Resistance weapons. The .0 job gear gets named weapons, and for Warrior have all been FFXI weapons: Farsha in Stormblood, Chango and Skullrender in Shadowbringers, and the Gigantaxe (usually spelled with a space) in Endwalker.
By my reading, either the trend stopped in Stormblood when relic weapons stopped getting unique names, or never stopped because every time WAR gets a level-cap weapon, it's one it had in FFXI.
