Honestly, the DF situation seems to have gotten better since that horrible (truly, truly horrible) first month. I can't say I've encountered any jerks in the last month or so and I do at least four WP runs most nights.

While with 24 people you are more likely to run into bad players/jerks they are also less likely to be able to significantly affect the run. At the end of the day you have 6 tanks and 6 healers. If one of the jerks is a tank, but one of the other parties have 2 i90-geared tanks in them, donate one to the underperforming team and have their healers focus him.

Personally I'm hoping for at least sections where all 24 people are together and the place just floods with enemies. That would be more fun to me than splitting into three teams of 8.
