Next dumb move they did was use a battering ram on the main door. I can't stress this enough and everyone in group chat heard how happy I was when I saw the battering ram (Never ever use a battering ram especially on the front door!) Anyways, Stu and I got out our burning oil and so did some others and it doesn't matter if you have a siege shield, but 3 people using burning oil on you will kill you. So their first attempt at the main door failed. Next, believe it or not they tried the ram again! We did the same thing and they failed again.
In the meantime I had a quest to kill 20 dragonknights. While I was using my oil I could see the count go up each time I used it. Use oil...Killed dragonknight 11 and 12. Woohoo..
