For anyone joining the game around 2021 onwards: Welcome to the new expansion experience. As with any new content, people don't know it perfectly and it is expected there will be hiccups. This is the same thing that happened for ALMOST every single trial when it was "new". Titania was similar, and now it's not difficult because the majority knows what to do.

Also keep in mind the majority of people doing the content are doing it at around the minimum iLVL to do it, as they are leveling alts/doing the MSQ. We're not at a point in the expansion where everyone is being sync'd down and essentially overpowered for the fight.

If you can't clear it due to visual issues, there are settings to reduce visuals until you know the mechanics better. If you refuse to take advantage of those options because "MAH IMERSHUN!!" that's a you issue.
