I wish everyone felt this way. I'm the type that can't learn just by watching. I need to actually do the fight to get it to stick in my head. So no matter how many videos I watch, I'm not going to get it until I do it. If I can't do it because someone died and you start yelling about how we're all useless and need to watch videos and go do Titan normal (??? because that's totally the same fight...) to practice, I'll never learn.
Basically, if you want a party full of elite pros, you need to go shout or use your FC. Otherwise, chill. Understand that not everyone in the Duty Finder is a pro, and help them out instead.
