Technical details on spell downranking

[Zarathustra]

I wonder if they'll be taking another look at the encounters currently ingame, then? There's no way their QA team used only top-rank spells when in the testing phases of Ahn'Qiraj and Naxxramas.

I half expect this change to hit, and then complaints to roll in on the R&D forums saying X, Y, and Z encounters are nearly impossible now.
