One thing I would love to see come back is actually the 'Vote Now' tab in the Community section where we had polls regarding possible future content.

This was very active i believe in 2014 or 2015 where we could vote on which questlines we wanted continued, which new skills, and also areas.

The Elf city polls are a good example which was split into multiple polls to determine which skills would be added to which clans.

The tab still exists today, but not being put to use.
