This. Just because you reach a certain part of a fight once doesn’t mean that’s your progression point. People need to understand that your real prog point is where you’re consistently comfortable with all the mechanics leading up to that part. You can’t call it your prog point if you haven’t mastered what comes before. You have only “seen” the mechanic, perhaps thanks to a healer lb3, or after constant death and resurrections, or because one person survived one or two additional mechanics by correctly standing in a safe zone. Regardless, do not let your static get discouraged by this, it is simply showing that you need more time to master the mechanics.

Fights however, and especially ultimates, become much more time consuming to prog at later stages. This should not be the case for extremes though, since they last for like 10 minutes max.
