RAW_
SkyWars/BedWars oriented ranking built on the legacy (1.8) armor model where one armor point is a flat 4% reduction with no toughness and no damage-strength scaling. Only relevant enchantments influence the choice (Protection always, Projectile Protection optionally). Niche enchantments (Fire/Blast Protection, Thorns, Unbreaking, ...) never out-weigh real defense - they only act as a final tie-breaker. This stops the module from picking, say, iron with high Fire Protection over plain diamond.
