This just in: In addition to the latest Patch 2.3 updates we just noted, the various heroic instance keys will no longer require "Revered" reputation with the various factions around Outland. "Honored" is now sufficient to get you in to Heroic dungeons everywhere.
This raises myriad questions: Does this devalue the heroic instances at all, or does it simply open them up to more players? Is it a slap in the face to all those who had to grind their way to revered up to now, or is it just the natural progression of opening up content for more and more people to access as time goes by? Will anyone run regular Steamvents, Shattered Halls, or Shadow Labyrinth when they can just skip to the heroic versions? Will this get thousands (or millions?) of players who got burned out on the rep-grind back into the game?
