Just want to say that I had similar fears and at first only ran dungeons if there was at least one guildie with me, but I’ve started running PUGs too and I’m still a newbie (first level 50 this past month and CP<160) and people have generally been great. Once one person may have left when I announced I was new (but they didn’t say anything so may have had nothing to do with me) but I’ve never been kicked or insulted or anything like that. Groups often go ahead on the trash mobs while I get a quest or have to wait for an NPC, but that’s okay. I’m sure there are unfortunate exceptions, but my experience has been positive; people are understanding and wait a minute if someone dc’s or has UI issues and some people have gone beyond and been quite helpful.

I had an awesome time in Moorgrave Fane last night because at least two of us were new to the dungeon and another person was working on a new role for them so one of the fights took quite a few attempts but the win was so much more rewarding for it being a challenge that we worked to overcome together.

I hope you find a good group but I hope you’ll give PUGging a try on occasion!
