EverQuest II's dungeon finder was a hot-button issue. Some players wanted it, others predicted the doom of grouping, the game, and life as we know it if the feature got implemented. Fast forward a few months and now the dungeon finder is hardly used aside from guildless mid-level players looking for a quick PUG crawl.
Sony Online Entertainment has announced a couple of tweaks designed to incentivize the mechanic, and EQ2Wire has the relevant developer quotes as well as a bit of commentary on the process. In a nutshell, SOE is adding contested dungeons and daily rewards into the mix. While this may result in a temporary upswing in dungeon finder interest, it doesn't address the primary reason veteran and high-level players shun the mechanic. The system still won't take player gear into account when forming parties, so it is therefore quite useless when gear-dependent content -- like any of the dungeons from the Destiny of Velious expansion -- is the goal.
