Over time, we have felt like Valor has taken on too prominent a role, to the point that it risks becoming more important than actual boss loot. This is particularly the case when the tier sets are available on the Valor vendors. We think killing dragons and ransacking their hoard is more epic than shopping at the magic armor store, so we want to shift back toward boss kills being the primary source of epic PvE gear.
