The Ares and Koenig sets (The Wootz armors for DRG/Tank) were salvage/sky respectively so in-line with that it might more sense for them to have something like the Nashira set from Limbus or the Shadow Coat set from Einherjar if they're going for a "Throw-back to XI 75 Endgame feel". The Igira armor was very iconic (To me at least) back in XI's "peak", I wouldn't mind seeing it in this game either.
