I run an FC on Excalibur and of our 85 players, approximately 20 still play regularly. That is an attrition rate of approximately 75% since launch. Judging by my viewing other company profiles of late, this is a common situation across the entire server and my guess the playerbase as a whole.
One of the things that our remaining players have been looking forward to as a goal for our FC was to obtain an FC house - it was something that brought players together and gave us motivation. We currently have pooled 2.6 million from our members to date, which is only about 10% of the required 20 million for the smallest, worst plot of land available on our legacy server. As many others have stated, without a low-level entry point to the housing feature, this has been extremely discouraging to those hoping to enjoy this coming content. I fear that even more of membership, and the playerbase as a whole will be discouraged to the point that they may stop playing.
