We all hate noobs, that's for sure. But we aren't perfect, unfortunately. I'm sure at least most of us have acted noobish before. I don't just mean something like not knowing what to do on your first Jhen quest, we all do that. But if you just started acting like a noob.
As for me, I can recall one main incident in which I acted real noobish. I had finished a quest, probably Jho, and no one was in the city. I was kinda in a bad mood, and I didn't really feel like playing, or at least not like fighting Jho, but, either way I found a Jho city, since I figured it'd be good to keep trying to get a gem, and we did the sandy plains quest. I ended up dying real fast, so I got mad, said f this, and abandoned. After I got back to the city, and one of the guys called back and called me a noob. I didn't want to admit it, but at that moment, he was right. I felt really bad about it, and I still do. Doing Jho can be hard with just 3 people if you're not experts, and if you don't all have really good weapons.
So, if you have acted noobish before, post about it in the comments below.
