Which is worse?
Someone asking for help and admitting they are new and either getting the advice they need or being told politely: "Hey I'll help ya out, but also know there are good guides on the net that could help you as well so if you like to can look at them."
or
An experienced going into a low level dungeon knowing there might be new people in there. Telling them they suck. Telling them maybe they should change classes because obviously don't know what they are doing. Cussing, putting them down saying they should go read a guide or gtfo of the game. Kicking people out of a party because they are new, kicking people out of a party because they don't have the 'experience' that player feels they should have. Having an older player complain the whole run about how bad new players are and making them feel awful, or just saying 'oh god a n00b I don't want to run with a n00b - and leave party etc. (yes I have seen many of these things said to new players)
I'd rather someone say 'Hey I'm new, any help/advice' and helping them though it but also letting them know the resources are there if they choose to use them. Than be rude and make people feel like they are worthless. If a child just learned how to start coloring for the first time and colored outside the lines would people tell them their pictures sucks, learn to draw within the lines or gtfo. Probably not, we would tell them it's beautiful and then teach them to color within the lines. So why do players treat people who are learning like they are some plague that is wrong?
Have you never asked for advice from someone in the game be it DF, LS, FC? or did you do all of your learning though tutorials and videos, never once asking for help within the game. When you started a new class you'd never played before did you ask for advice from people or did you only rely on what people said online and in videos on how to learn it? If you never asked one question of people within the game and learned everything in this game on your own with the help of tutorials and videos only, then yes I suppose you can have that view towards others.
But I doubt the above is true, so in short... people are putting them down for doing what we do all the time. I know I ask for help from people, and I'm not ashamed of it.
