Interesting. I'd worked out that a few of them did need other emotes, but it seemed to be linked with variations in the hint text - eg. instead of the usual "I looked out over the landscape" text, that one line might change to say "I sat down and admired the landscape". (One spot in Gyr Abania had me agonising for ages before I realised they'd inserted 'night' into the otherwise standard text.)

I couldn't see any incomplete entries remaining in Coerthas that indicated a different emote to 'lookout' and I didn't think there were supposed to be other variables for the Heavensward entries.
