My builds right now:
Trapper: Whispers, Enduring, Agitation, Thanatophobia (Agitation because with Trapper it's important to be able to choose your hooks and save time. Thanatophobia is a recent addition for Brutal Strength. Stalls time, makes my Trapper late game really strong.)
Wraith: Whispers, Enduring, Nurse's Calling, NOED (NC came for STBFL and NOED for BS. I might try Thanatophobia instead of NOED because NOED is such a cheese perk. I also switch between NC/NOED and Bloodhound/Sloppy Butcher currently. The key to success with Wraith is to always use hooks to secure the next chase, and thereby to occupy three survivors with every hook and to try to keep that cycle up as best as possible for the entire game.)
Billy: Whispers, Enduring, Deerstalker, Shadowborn (Just backrev people and then control the slug farm. Shadowborn replaced BS, but it really helps with chainsawing and also in regular chases.)
Nurse: Whispers, Shadowborn, Nurse's Calling, Stridor (I switch out Stridor for Deerstalker sometimes especially if I see toolboxes in lobby, and sometimes I switch Nurse's Calling and Stridor for the BH/SB combo.)
Myers: Whispers, Enduring, Insidious, Dying Light (I don't often play Myers, but when I do, I hunt down and Insidious-camp my Obsession to death. Immersed as Pure Evil.)
Hag: Whispers, Enduring, Agitation, Iron Grasp (I put people into the basement and they never get out, only more get in. But now after 1.5 I might change my playstyle and loadout with her.)
