Everyone's talking about newbies like they'r some kind of endangered species which people are hunting for.
Newbies or not newbies they are all people, assholes can be newbies or veterans or anything in-between.

Through leveling of all my classes to 50 I met more newbies acting like assholes than anything else.
And when it comes down to fresh 50 dungeons it's often even worse.
Newbies trying to teach you the game because they did something once (or watched an outdated video) and think that's the only way to do things.
Refusing to listen to anything you say to them.
Or just throwing some other outrageous bullshit at you because they think they'r some kind of special snowflakes and they get to do as they please.

So, no I don't see why there needs to be more unnecessary newbie protection in favor of the newbies.
Where it is people that take/waste their own time on helping newbies out which should be the ones that get protection/rewards.

I do think the game itself does need to teach newbies the ropes better though and make it clear that it's a team game and that they will have to work with the team and not see the team as some kind of slaves that are there to do their bidding.
