I know for me FPs are just not very accessible. I only have time for maybe 4 hours of play a night. So standing around in the fleet makes quickly starts to feel like a colossal waste of my precious free time. An LFG tool would be a huge improvement, so I could wait for a FP group but not feel like I'm wasting time.

The long cooldown on the fleet pass kills it, as well, I think. If it was just a matter of finding the people on the planet where they level and then everybody uses their fleet pass it might be easier. Sure, it's a matter of a mild inconvenience, but then when the inconvenience is enough to effectively waste all that content... well, I think it would bother me if I'd developed it.
