The Final Day needs an iLv Sync. NOW.
I've taken a bit of time to go back to Endsinger, and depending on the iLv and skill of the party you get, Endsinger is now being killed before she gets to her end sequence that includes the Scions of the Seventh Dawn. This is akin to skipping cutscenes in Castrum Meridianum due to the fact that the end of the fight LOSES ITS IMPACT.
In DF, we were able to reduce Endsinger to 22%; and was killed right after G'raha Tia spoke. This poses a potential issue, as you get an increasing buff each time they speak.
With a controlled PF group, averaging iLv 636, Endsinger was reduced to 22% without Echo, 17% with 10%, 1% with 20%, and 0.1% with 30% or more(with smart holding); but could not be pushed any further.
This presents a major problem with the fight design, as the soundbites the Scions do at the end sequence are not played due to Endsinger dying after she finishes her own soundbite. I highly recommend that iLv Sync to 560 is forced to allow the fight to play naturally as it did during 6.0.
