armor weight

adding armor weight will change the combat sistem that right now is a rush to a full netherite. 

By adding weight to armors players will have to decide if is better being faster but at the cost of protection (like with chainmail or leather) or more tanky with diamond or netherite. you can mix some armor sets to decrese weight so there will be more variety in a fight.

Armors from iron up will make you sink faster in water and make it hard to float, will also consume more hunger when sprinting and you will deal damage by falling onto someting (longer the fall heavier the damage)

special mixes of armor can give some weird reaction, for example having an iron chestplate, netherite leggins and gold helmet and boots will make you able to light redstone components when hit or while running)
