I would agree, but also know its absolutely the most ridiculous thing to wait for 45min to find a healer to run with your group, or that 4th person.
The other day I was hanging out in the fleet, you know, for 2 hours being a dps waiting for a group to join for a hard mode. When I saw a post LFM DPS HMs. I jumped on it, thinking I wasn't typing fast enough. They invited and my two hour wait finally came to an end. They said they have had difficulty finding a DPS all night. I was like WHAT? I've been here for 2 hours reading chat, doing shout outs. They were off in Ilum doing dailies and some pvp, doing shout outs there.
Point is, no one wants to hang out in one area to communicate with everyone else for something as trivial as finding another member to run a flashpoint with.
