The biggest wave I've seen so far came through around 3:30am. It was almost like 3 waves one right after another. There were only about 10 or so people around so it didn't go as well as earlier waves. At one point I got trapped in the healers building with a lich standing inside right next to one of the healers. That was a bit interesting. The healer kept trying to res me but I gave up and stayed dead after the lich got me twice as soon as I was resed. I had to call for backup from a guildmate. Thanks Sam.
