I used to be a hardcore raider as well I can often remember the 12 hour slog marathons in Molten Core lol. Currently trying out ICC 10 with a few RL friends and my boxers trying to work out if I can take down the first boss or not. We seem to do ok on Trash mobs tho be making a serious attempt later this week.
Oh, you definitely can. The only question is if your buddies are patient and rich enough to go through the learning it will take to do it. A couple of us have soloed him already, so you are just a bit of preparation and wipes away.
