The Party Finder on Diabolos hasn't been as busy as it is now since Heavensward's launch. I'm seeing a general uptick in the number of people participating in content, rather than the reverse, here.

I have talked to a few people that probably won't be doing the Anima grind. Some of them are folks that didn't do the Relic/Zodiac grinds in ARR, though, and I would expect them to not like this grind as well (since it's arguably worse than anything we've gotten before).
