The midchapter actually changed my default Survivor and Killer builds
My default Survivor build went from:
Iron Will/Inner Strength/Dead Hard/Spine Chill
to
Iron Will/Circle of Healing/Dead Hard/Windows of Opportunity
My default Killer build went from:
BBQ/Hex Ruin/Hex Undying/Corrupt Intervention
to
BBQ/Deadlock/No Way Out/Corrupt Intervention
The buffed perks and the new boon meta actually shifted how I play now, which is pretty cool. Usually the new patches just introduce new cosmetics with no meaningful gameplay changes.
