Pre-3.3, that was 3200 damage absorbed, lasting 20 seconds I believe, may have still been 10. Either way, the damage absorbed was doubled. Noticed this while in ICC10 tonight.
This was both a notification to other players, and an opening to ask if anyone else has noticed any items changed that weren't in the patch notes.
