Coeurl is a medium server but on the lower end of medium servers. How active people are depends more on your FC (and which FCs are friends with your FC) and linkshells that you use. This might disqualify Coeurl, but I am not sure. I have a small FC, and had 10 people active in the last day.

Coeurl has small houses In Mist and Shirogane. Mediums and Larges are hard to come by.

The crafters on the server are very nice, and usually are good with optional tips given the person needing an item provided mats. If you are a crafter, there are crafting FCs. I am the leader of one, and I know Lady Lucy is the leader of another. There are also large FCs that like to add crafters.

People on Coeurl are very laid back for the most part. Drama is rare and doesn't last.

I'm not sure about maps and hunt ls. Hunt is usually done by train. FCs like to do maps.
