Maybe its because I exclusively do pugs and never do LFR, but I have gotten more loot from the current system instead of personal loot. I did not raid that much prior to this expac, but I do remember doing an entire Nzoth raid run and getting I think a single pair of legs from like the third boss and that was it, and I also remember doing an entire Castle run in shadowlands and getting only like 2 pieces of gear.
I raid usually with half of my guild and half randoms because we are group of about 10 people and arent really good enough to do a 2-2-6. So we raid a 20 man every week and I have absolutely no issues getting loot and I keep seeing people post about how they havent gotten any loot in weeks, and that personal loot NEEDS to come back, when Im having a lot more fun discussing with people in the raid where the loot should go and only letting people who can equip the gear roll on it.
