First of all , there is no adult way if you think that there is a great distinction in-between children and adults , you are the greatest infant , second of all armor is subjective so yeah ofc they can be made "better" or "worse" in your or my opinion.

Think King's fall armour and you have an adult version of the monsters set. That's what I mean, this looks childish.

The childish look of those sets should be cultivated, after all we are playing to have fun!
