event boss is scaled to 1 person if people join once someone has attacked boss.

I feel this should be fixed asap as this makes things ridiculously unfair, people are using this as a method to kill the boss making runs 4 times faster as 4 people are attacking a boss scaled to the difficulty of one person, its easily fixed make it the same as previous events where you cannot enter of the boss has been attacked.
