Untradable Evo Ring II and Tradable Evo Ring II stack.

... What? The only way to wear 2 evoII lv17 is to keep one untradeable.

Yeah, I noticed that after I posted it that I was being idiotic because my other ring was level 16. So they stacked naturally.
I personally think we're better off making it tradeable now, since it's obvious that it's getting patched. It's being posted everywhere, and it's going to screw you over in the end.

not my SS, just showing.
