Did Void Ark a little while back where me and the other healer were synced with each other without saying a word. At this point in progression, you barely need to heal anymore (at least in the groups I'm in) so the healers just stick to Cleric unless needed. Me and a WHM were flowing through everything while taking turns healing and stance dancing without saying a word.
Soooo nice to have @_@
