Wooh, this is a change I like.Transmog
-The ability to hide the chest slot will be added in the next update.
-A long term project is to loosen some restrictions over time so players can have more self expression.
This feels like it should have been an option from day one of transmog options. Some probably would argue its silly because those without armor would get injured more, well let me direct you to such lore rich characters as such.
Fact of the matter is theres been characters in warcraft who have in their badass way looked the part without wearing chest armor, and I think the only reason a lot of people have thought it shouldn't have been an option is just because it wasn't an option.
I intend to make my orc warrior, lightforged draenei paladin, and most of my shamans this way
