Like many of the people here I'm a former/current WoW player who decided to check out GW2 because of the hype and I really must say......I'm enjoying it! My first character is only a level 13 but I'm enjoying the dynamic events, the spooky doors that release bosses, the personal story, and I just now downed the Mad King with a group of 4 other players in what was an epic multi-level battle that took a LONG time to complete. Just sick.
I'm kind of suffering through the same "What will I do at level 80" feeling that others are because I want to experience all of the major bosses multiple times and not just once and since bosses like Shadow Behemoth have to be triggered I'm afraid I'll get bored just sitting around waiting for someone who happens to be on that stage. They need to put him on a timer or spawn him randomly, same for all of the "meta bosses" so that way we always have a sick boss to fight. Any which way, the bosses I have fought, including the amazing Mad King, have been absolutely phenomenal and I'm looking forward to more of this kind of epic encounters.
