We are 8 hours into the new world boss. 11% of the total damage to this boss has been done. I have just got my first attack in. Unless interest goes down now that it is daylight hours here in the states (that won't happen), this boss is doomed to pass in less than 72 hours, my guess it will be gone in 60. even at 72 hours, an insomniac hitting at exactly every 4 throughout the life span will only get 18 hits. Not enough to unlock all of the bonuses. This has been going on with the last world boss too. I have yet to collect every possible for my level as I play 3 or 4 times a day, not continuously. Don't get me wrong, the world bosses have a great place in the game. Here is a thought. Change the attack frequency or change the strength. The world bosses in Zombies hangs around long enough to get your 25 attacks in and makes it worth the challenge. I would venture we wont see anyone with a dreadbiters fang for quite some time.
