That's the complete opposite to what I want to happen lolWhat I think needs to happen is, more armor needs to have multiple stats for different disciplines to do something with them. I would like to see crafting stats on the Plate Armor, An armorer being empowered by the armor he/she creates. and the funny thing is, Plate armor Favors Armorer >.> but there is no reason for them to actually wear it: no crafting stats.
As I said before Doublet could be a second choice to double vest (but make it Crafting only)
Pointing to the text I highlighted, If you do this it basically means any class can wear any gear, its a massive problem and the devs are looking at the rebalancing and restriction of gear (check the in development sub forum)
What you are suggestion is making armour ever less unique kind of like the whole armoury problem with equipping skills across classes. (its just watering everything down so everyone can be everything and wear everything)
From a role player perspective wearing plate armour to craft would be kind of silly, many times heavier than leather/cloth armour and hard to move in.
