Yep. Unfortunately there are a lot of mediocre tanks that don't run through mobs and spin around so they are always facing away from the party. It's kind of funny to watch them play like a DPS, because maybe that was the only job they knew how to play before.

Doing it is more than just getting cleaves away from the party but also preventing damage in directions that you can't auto-block or get a parry proc which is so useful for jobs like DRK that have skills to mitigate damage when they get one, even though you can't really depend on procs all the time.
