Ive gotta disagree with the main poster and agree with the others LI is a tier2 flashpoint it yields higher gear because of this therefore it is a harder hm to work towards its not one to jump into as soon as you hit 50 its more of a go in there once you have geared up a bit the reward is a nice rak chestpiece.
I also dont think people are going to quit because of it its just a stepping stone of difficulty once geared enough its an easy fp to skip through
My advice gear up and enjoy it
run some ops and pick up some free gear on the way
Good luck and enjoy the challenge
