"Anything that we should try?

Yoshida: Well, I think working on mechanics should be the first priority rather than focusing on damage. Try a section 10 times, and give priority to getting through that part of the fight 10 times without any issue. If someone doesn't understand what to do or makes a mistake, practice for that person. If you proceed through the fight without everyone on the same page, the differences will get exacerbated. Instead of setting really high goals, work on the fight one phase at a time and you'll get better results. Let DPS be the last thing you focus on. If you're playing with a focus on DPS from the start, you'll be neglecting how to properly deal with certain mechanics. It's a much better goal to be certain that you can get through the mechanics of phases instead of being able to reduce the boss to a certain HP percentage. Part of avoiding the mechanics has nothing to do with DPS. Once you are at a point where all eight players are able to cleanly deal with mechanics, that's the first time you should start thinking about DPS. The first goal should be to kill it before timing out, and then you can think about ways to shorten the time spent in each phase."

The thing about this is, people want high DPS right away, expect everyone to know ALL the mechanics right away from watching videos, and demand TeamSpeak.
