Isn't this more of a "there is no point in doing a raid if you're not in a static" case than a "the raid community is dead" case of thing? Also most raiders have a static and I doubt they'll bother going with a duty finder for raids as they'll have limited control of who join them (hello trolls waiting for the last second to screw a fight). Also what were your settings for this raid? I would not be surprised that only those who have yet to complete it would use the raid finder while those who have already done it are in a static and find no use of going through the raid finder to do content they are already doing with their static anyway.
