A lot of people are, for some reason, just fearful of dying.
Dying is part of learning fights and has no real downside.
When you wipe to a fight, you start over and do it again.
Often, people will be supportive and help you with whatever you struggled on.

I will never understand people who play an MMO but have anxiety doing no pressure content when so many people are super nice.
I'd rather the game not go back to making every normal difficulty fight a piñata that spits out free loot for just hitting it.
