I can understand the trouble here. In XI we had events that were raid like but had names. These names came from a background given to the content, and therefore gave it meaning and purpose. Yes fun is important, but so is a reason to be in a place aside from the items that drop. I'm going to be happy with content to play but even if this were part of the Company system Id rather call them Company Dungeons than just a raid.

A large problem comes from localisation which I think has been a struggle when translating information. In jp a broad term they use is raidodungeon. The combination of raid and dungeon. This causes problems when trying to tell players about incoming subjects when the players come from varying games and backgrounds.
