Dawntrail's mediatour dungeon was already cleared without healers.

Group of sync'd lvl 100's in the expansions first dungeon nothing shocking about how they didnt need a healer. If it was a actual lvl 100 dungeon then that would be something to worry about but until that happens..not worrying.

Synced zot at 90 is harder than any of the 90 dungeons

Not sure how suddenly only the 100 dungeons are going to be hard
