There is no direct nerfs or echo right away because they want to see how many players clear it now that the lockout is gone. To see how much echo or adjustments they need to add. They said at fanfest they would wait a few weeks before making adjustments.

The content is actually naturally nerfed at 2.4 because people have access to higher ilvl gear, tomestone gear, final coil gear that did not exist when 2nd coil is current. I wouldn't expect any echo/nerfs till 2.43 or 2.45.
