Remove the lockout, keep the loot lockout. If people are so worried about selling runs then make it against the ToS and you can report them.
Lockouts are a detriment mechanically in terms of play and socially in terms of both the server at large and FCs themselves. So yes please, but keep the loot lockout as a way for SE to buy time between contents.
Anticipating response:
Q. What about players who will not use their "roll" when the loot they want isnt there? No lockout means they can just go again till they get what they want!
A. Repeating the hardest content in the game to get one piece of gear you wanted isn't the worst thing I've heard of, however if that was a significant concern you could make it so your first run is your "roll" run.
Q. Why do content that wont earn you anything (after you use your roll), even if there wasn't a lockout?
A. What I would like to see is rewards for doing such content, like seals (sol, allied) or even better opportunity to earn vanity or more particularly FC vanity. Doesn't need a reward though... I do Relic story/Titan for my FC that need it for relic, and I don't get or want anything from it.
