Sombody in a stream wanted this posted on the Fourms because he didn't have a Fourms account. He wants to remain anonymous but this is what he has to say.
"With everybody running heavy I have proposed a idea to balance all armor types. This is how it should work. If you wear 5 pieces of the same armor type you'll have access to that armor skill. Say you wear atleast 5 light then you'll have access to harness. If you wear 5 medium armor you'll have access to shuffle, and if you wear atleast 5 heavy you'll have access to immovable. This would balance all armor types".
