Any idea what is in patch 2.57?

This isn't meant to be generalized to everyone, but sometimes the reason DF groups fail is because the experienced players just don't explain things well enough.

While that may be true, honestly it's not experienced players job to teach. If a player walks into DF coil and has no clue what the fight entails... how it works... anything about any of the mechanics... that's on them. It's not on the rest of us to teach them. If somebody there is willing to teach, more power to them. I do that quite often, with mixed success. But make no mistake, the group isn't failing because they didn't teach the person. They are failing because that person walked into end-game content without doing even the slightest bit of research, and expected to be carried.
