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

[shape]

Many of us old school players do look up guides and get as much information as possible, why well for example I main tank, if I do not know my shit, shit probably will not get done.
We have a sense of responsibility to not fuck others over.

Have I had to do blind runs for progression in my younger years ? yes it was hell, did we also use guides/information as soon as it was available or release our own also Yes.
Information is power.

To sum this up many people go blind and outright refuse to use guides, even after the first run, this is fine as long as they learn fast, if they do not be prepared for the possible scrutiny that comes with this choice.
Information is power.

As for the actual problem the new player was not in the wrong for not looking up the dungeon but they where for not being ready to do said dungeon, yes this includes going in as a class, not being geared in presumably all three areas armour, accessories and most important the weapon. This all just points towards the type of player who does not care how they effect others experience.

As a mentor I would point this out and try to help. But to be honest the best solution would be to have them leave and sort their shit out, after they had received the knowledge they required. Dying 8 times in any of the dungeons, not raids (24man) is abnormal. Yes they would lose time but coming back with appropriate gear and a job would give him an easier more enjoyable run as well as for the other three people in the party.

Why is my mindset the way it is go play with J players and see how they do things. This is something I did in 1.0 dam it was fun.
