Q- i think you should make a thread with all the info compiled into one place. also- i was lvl 97 at the event start not 87

and you hit the nail on the head about HK's bosses flattening out at the end!! mine got harder and harder for each boss. her's didnt. thats why i said nothing makes sense anymore haha. you would think all the bosses, regardless of level/allies/attack scores would follow the same curve!
