In the Throne of Thunder, the Normal and Heroic raid bosses have a chance to drop an item with a new Thunderforged designation. (Normal / Heroic) Thunderforged items are 6 item levels higher than their standard counterparts. Bonus rolls can award a Thunderforged item (again, only in Normal and Heroic), so probably the only thing to plan for ahead of time is having Lesser Charms ready and waiting to exchange for Mogu Runes of Fate.
So this means those of us who don't have a regular raid but do run LFR are SOL?
