There are 2 things that I would like to point out specifically regarding the Bismarck Extreme trial, without falling into the DPS/parse trap discussion.

The first is that a lot of people are wasting buffs and big cooldowns on the adds. If you literally save everything for that moment you board the chitlin your DPS will skyrocket. This just involves people not knowing the fight. Food (and possibly stat pots) can help out a lot here too. Worried about not killing the adds in time? Perhaps your group is triggering the Dragon Killers too early. They should be used as late as possible to buy as much time as possible to take down adds, heal up, and stall for cooldowns to reset. Again this boils down to not knowing the fight (not triggering Dragon Killers at the latest possible time). Discuss this with your group, preferably BEFORE queuing up so you can get ready with food and pots (perhaps you can be a philanthropist and distribute some to your group if you're so desperate for a clear).

The second thing I want to mention is that THE CHITLIN CARAPACE DOES NOT NEED TO BE KILLED ON THE FIRST DRAGON KILLER SET. This single fact alone is what's holding a TON of people back from getting their clears. If you can't do it in 1 pull, then yes, your DPS is low. But it is not the complete failure that everyone thinks it is! It just means you will have to work that much harder on the final phase and do everything perfectly. You may even need to Limit Break on the elemental dragons (gasp!). It's such a shame that people are stuck in this mindset that everything has to be done ONE certain way and CANNOT be done any other way. It is a really sad experience to see wipes (and consequently disbands) because people want to force "all-in" on the Chitlin (stay until it dies, or we die). Also a shame when you can't clear the dragons in time and people refuse to Limit Break because it's "necessary" for the final phase. So I just wanted to point out, it is okay to not kill the chitlin on the first pull. And it is okay to use Limit Break on the dragons. You can still get a clear with both of those things happening.
