7 years of playing WoW and the only game experience that LFG changed was the amount of time it took to get a group together.
one more thing changed as well - players were doing even less quests then before. to the point when you could actually do almost no quests at all, just level on doing lfg dungeons.
and since SW:TOR is much more story based, maybe Bioware doesnt want players to level by running same flashpoint 8 times and then mowving to another one, without being ;out in the world' at all.
just an idea, it also possible that they simply dont have a tool for it yet
