Looks like theres a bunch of act 2 and 3 defeats that havent been implemented but have the details floating around. They'll probably be added eventually
I agree with the collector though. Dealing with the start of the next act is just impossible...
Also, clearly you've never tried a fantasize+conditioning+brainwashing+lust crest build. Straight up instant killed everything in act 3, including elites AND the act boss
