The W2 remaster is an opportunity for W2 to have a better, bigger future than that of a tiny, dying game.
Every person who spends money on this old game is looking for the same thing we are: they want to have a fun time.
Every "worthless newb" is a human being. In real life, they are office workers, cops, lawyers, managers, politicians, musicians, hotel staff, parents. Many of them are adults with limited free time. If they have a good time at W2, they are likely to play again. If they are treated rudely, told "Get lost, newb" and the like, there are countless other games, movies, shows, and things they can do for fun other than W2.
It's in the best interest of pros who love W2 and enjoy the glory of being great at something to have a game that is active and popular. It's in your best interest to be polite to newcomers, newb or not, because the future depends on having a playerbase.
I'm not saying you have to play with them even or make friendship bracelets for each other while braiding hair, just that you can say "We are playing with friends and need your spot" which won't leave such distaste in a person's mind towards the whole game experience and think "Wow W2 players are dicks".
This is an opportunity for W2 and it would be a mistake to apply the "ru welcome" (ie GTFO loser!") that successfully drove countless people out of ru.
The new "cool" is being considerate, welcoming, and friendly and forgoing the high of feeling above someone for a few moments of glee while bashing someone who thought W2 might be a fun thing to try.
Don't assume there is an endless stream of newcomers. If they have a bad time, they will find something more fun to do.
Not much glory in being "the best player" among 50 in a world of 8 billion.
