Apparently, new player means no one can look anything up anymore

It's honestly not hard to learn the basic mechanics of this game. And, if people are so inclined, they will look outside the game for more information. We also have Hall of the Novice now.

That being said, if someone is struggling you can offer to help. But this goes both ways. I believe they should also realize that something is not going well when they've died 8 times, and perhaps ask for advice. Unless they don't care enough, in which case, they are pretty much dead weight to a party.

I personally like performing well, so I watch guides before doing new content if I think it's necessary. Especially since seeing and doing something are two very different things.

Edit: It's within your right to hop into dungeons without having watched a guide. A lot of people do just that. But wanting to experience a dungeon blind is not really an excuse for bad play. Most dungeon enemies/bosses follow similar patterns. You can also ask if there are any specific boss mechanics you should know about if it's your first time.
