I had the same conversation with the same person.
I was a lvl 10 ranger at the time. I was soloin with my flag up when he asked me to join.
He got real mad when I asked questions about his party. Called me a snob and an eliteist. I stayed calm and even tried explainin to him that ranger was expensive, and if I died, I lose more than a couple of xp b/c food cost so much and what not.
He wasn't havin it, I was a noob, he was gonna pwn me with his lvl 53 whm, blah blah blah.
Newbs today got no respect.
