At some point of game, everyone will be wearing or crafting the same gear set. Actually, aparently almost players want wear a Silent Armor with the 2H sword.
Each set gives to player a specific attribute bonus, so if I want str, i have to wear Darfari, Kambujan, Hyperborean or Lemurian Warrior set.
But there is no medium set with heat protection and str attibute bonus.
New sets will come with DLCs and probably this sets will have its own bonus, but always will exist a gap.
My suggestion is make the attibute bonus works as runes for example.
We could learn this rune recipes as any other recipes ingame (boss room with text walls, thralls, journals, etc).
With this runes, we could changes our set attributes freely.
