I'd rather the new normal mode gear be something between 509 and 517 (fully upgraded 509 gear). Heroics are typically a full tier (13 iLvLs) ahead of it's normal mode counterpart and if normal mode was 509 we would only be getting 522 gear from heroic bosses. Not that 522 is low by any means, but it's only 5 levels higher than our current heroic gear.
