[Suggestion] Armor set buffs
Adding buffs to a full set of a certain armor type should give a bonus stat. Also classifying the armor into weights like light med heavy. Then give the type a bonus as well if fitted with all pieces from the weight. Example 5 piece bonus to light, med and heavy armor. Each type of armor would need a protection number based on the weight of course. In short mmo style armor stats and customization.
This will give the ability to mix and match armor and to min max for certain events. Bonus examples could be stealth in certain biomes, health, health regen, stamina, stamina regen, movement speed, and physical/elemental/storm resistances.
