Unfortunately, most of the guildhest mechanics are relegated to open world content like fates and maybe hunts. Dungeons kinda had/have a few like Aurum vale; where you need to kill the morbol eggs or you get overwhelmed, but you know how people feel/felt about that dungeon. A Realm Reborn is the height of XIV's content design in my opinion; the jobs just needed Stormblood-level mechanics.

Ever since heavensward every dungeon is 2 mechanics-less pulls between 3 bosses. That's the height of cbu3 creativity and quality.
