sure you can help out a new player but why insult them by calling them a "noob" ?
"noob" is an insult, a derogatory term, if you need to call them a name call them a "newb" or a "newbie" but why call them anything? if you want to help just help them.
as the saying goes,... "nobody likes a critic"... you dont need to criticize to offer suggestions and to teach others what you have learned. Teachers dont help their students by criticizing and insulting them, they teach them.
per the definitions found on the web:
a noob/n00b and a newbie/newb are not the same thing.
Newbs are those who are new to some task* and are very beginner at it, possibly a little overconfident about it, but they are willing to learn.
n00bs, on the other hand, know little and have no will to learn any more. They expect people to do the work for them and then expect to get praised about it. Noobs are usually annoying and thought of as excessively stupid.
Do not confuse noobs with newbs, who are simply inexperienced players that are trying to learn and strive to become better.
with this being such a multi-language, multi-country, multi-culture game site any comment can be taken as a personal insult.
in my old guild, a player referred to another players city as "looking like a candy store exploded" because of all the decorations they had scattered around. This simple comment was taken as such an insult by the second player that a very heated argument erupted and ended up with the first player leaving the guild over it.
so i'm just saying that the rule should be something like
"It is allowed to refer to a new player as a beginner or a newbie and to offer suggestions for improving their game play using appropriate language."
help them by helping them, don't bash them by insulting them then expect them to be all ears listening to what you want to teach them.
