Well, I finally got to fight the Shadow Behemoth tonight! It was funny, there was a TON of people complaining that they never get to fight him on the map chat, and then all of a sudden the events that kicked him into gear finally began happening so we completed them all and fought the big guy. There were casualties, but the revive feature made it easy for us to help eachother out and though the fight was long we were able to take him down and get the chest.
Also, I've taken down a ton of Champion bosses lately with small groups, including the Blood Witch in Kessex that was an absolute pain thanks to the huge amounts of trash mobs that surround her. It took 8-10 of us to down her and that was with multiple deaths. I got me a nice helmet out of the deal on the first kill but I got nothing the 2nd time me and some friends downed her. Awesome (and hard) fight though!
Man, the community in this game is amazing, I'm over on Darkhaven and it's been nothing but great with the support the community gives and everyone seems to be working together......which is nice.
