There are still plenty of players out there, but what has happened is that all the existing guilds lost a percentage of their player-base, leaving a whole bunch of half-empty guilds that struggle to fill raids.
-- insert compulsory "my guild doesn't have trouble filling, you're just terrible" troll now --
What we need to do is consolidate some smaller guilds into larger guilds. Take 2-4 smaller guilds (that used to be big, but now have attendance issues) and smush them together.
The problem with this is that leadership of each of the existing guilds don't want to give up their babies. "We will merge, as long as we can retain control and they do things our way". But the sad alternative to this is that you've got a whole bunch of zombie guilds that don't really do much content.
Does anyone else feel this way?
