Post from Daelo FOUND HERE tells us that normal mode no longer as an attempt timer.
After each region's maintenance this week, raids will no longer lose attempts on wipes in Normal mode for Professor Putricide, Blood-Queen Lana'thel, Sindragosa, and the Lich King. There will still be limited attempts in Heroic mode. We will continue to monitor developments in Icecrown Citadel in the future, especially since the Heroic difficulty has been unlocked by a significant number of raids.

Slow Week prevented us from using all our attempts this week but we got let hm kill us once before everyone passed out at there keyboards :) Thanks everyone that pushed it as late as ya could to kill Sindragosa

Crank you volume Watch the Video and tell me it doesnt get ya pumped up to take out Icecrown! :)
