I looked at zybez market prices, it says 22m-23m visage and dfs 27-28,5m

 

how is that so??? even if you make one at oziach it would yield millions of profit..

I think it's because everyone just makes their shield and sells it, not bothering to sell the visage itself as that would be pretty dumb now that we have the assist system. Thus less sellers, not to mention rich people might rather get the dfs and not have to bother to hunt down high level smithers.

I guess because no one buys a visage, so when sold on GE they always sell at minimum price lowering the price eventually. The DFS is sold regularly and is awesome, so the price is higher.
