With blizz suggesting they may add ways to roll additional modifiers to items in the future, I assume people are not moving their gg items off LOD?

Holy what? What were they talking about?
Maybe they were speaking about the -%res that can be put on magic items right?

plz no

Not a guarantee, just one of like 100 ideas they are tossing around. It was part of the feedback survey blizz sent out. One more reason to keep your high end characters and gear on expansion.

Roll additional mods?

You mean my shako can finally get +1 find item
