Just for clarity's sake, once patch 5.2 is live,
Elder Charm of Good Fortune will only apply to
Mogu'shan Vaults,
Heart of Fear,
Terrace of Endless Spring, the
Sha of Anger, and Salyis' Warband (
Galleon). There will also be a brand new
Elder Charm of Good Fortune equivalent currently called the Mogu Charm of Fate. MRFs will be used in the new content being released in 5.2 including Throne of Thunder, Nalak the Storm Lord, and Oondasta (ooh, say it again!). They'll still be "purchased" with lesser charms of good fortune though, exactly how the current
Lesser Charm of Good Fortune to
Elder Charm of Good Fortune conversion works.
We'll be sure to let you guys know how various currencies (including Conquest and Valor) will work before the release of the patch, so you have some time to plan.
