It's a double edged sword.

A raid in FF XIV is only four bosses, with two difficulties.

If they allow you to run it once and be done, well then their raid tear lasts like...an hour a week.

It would be nice to have something in cases of bad luck. I had to run O12 6 times to get a shaft this week which was annoying. But on the other hand, if you ran it once and then had loot lockout, the content wouldn't last long enough.
