Because there are so many uniqe Armor sets, would it be possible to add a Armor set Feature just like in Terrarai or Hypixel Skyblock, where you can have pre buillt armor sets and you just need to toggle them on? I dont know how op that would be and what other problems it could create, but on the first thought this seems like an good idea.
[ P.S. maybe this idea was already mentioned, if so just ignore this post :). ]
