Even if they're newbs, they're still human.
If they ask me for help genuinely, I would help them (whether it's for G1 or G3 quests)
But there are certainly always those who are "noobs"
As for me, I was training Defense + Proffing my shield at spiders and a random player comes up and kills the spiders. At first, I was having a bad day and yelled at him, but he immediately apologized. I actually felt really bad for yelling at him
So yeah...
Another time, when I was on my level 6 mule, some level 1xx-looking player challenged my character. Perhaps it was because my CP was low? (it was just under 200)
Nonetheless, I beat him, and he was really surprised about me being level 6 total, while having the PvP skills of a level 1000+. At least he was a good-sport about it
