I don't like the mentality of "Read x guide/Watch x video before you do x dungeon". You shouldn't have to do that. I agree that it is helpful, I often do research myself if I am having a hard time with a dungeon or trial. However, people shouldn't be criticized for not doing so, especially if its their first time in a dungeon. Its not that hard and should even be encouraged for the party to provide hints and tips when it comes to strategy. Isn't that the whole point of grouping with others?

Part of the excitement of going into a new dungeon is not knowing what's going to be around the next corner and discovering this or that mechanic. In all honesty, 90% of the time mechanics can be boiled down to

1. avoid aoe's
2. kill adds.

Regardless of how people may feel, entering a duty is a time commitment; you should have already been prepared for that going in. If the party is going too slow or too fast for you, instead of making an ass of yourself, you should just suck up the penalty and leave. Go do something else for 30 minutes, as we all know, time flies quickly in this game. idk how many times I've scanned the clock an realized its 2 am, when I could have sword it was 9 pm the last time I looked at it.

Hopefully your next duty will be less of a headache for you.
