What was the design decision behind moving Brutus from his own room/arena, to a random spot in a long hallway?
I've been curious about this. Have any of the devs given a reason for changing Brutus' location? The patch notes are pretty thin on it:
3.15 > Brutus has taken the time to renovate his arena.
He doesn't even have an arena anymore!
I never thought this was a good change for new players myself, the mid act boss being at the end of a looooong winding hallway, when previously you entered his chambers in a controlled way. Both gameplay and narratively I just find it pretty weak, he's seemingly just hanging out outside his chambers (when he's too large to fit through the door), when a perfectly good room that's his is sitting right there.
*edit - something I just remembered too - he used to summon skeletons from the ceiling that would give flask charges back. Now you can fight him and completely run out without that "add phase" for replenishment. It really makes Brutus' change feel reversed: the current version feels like the beta, and the old version feels more like a Path of Exile encounter.
