While back then it was more reasonable to use it as we had BBBC still at a very high level and few quality forwards, people wanted Max to ditch it regardless because our game looked bad and everyone wanted an extra attacker instead of a cb. We switched to 4312 and beat Parma 7:1.
While playing possession football in 352 lcb and rcb build from the back. How many times we had to see Chiellini playing long balls or bursting forward because there was no other option available? Do we want to witness that again? Personally, I'd rather have Sandro and Danilo in those positions AND the additional forward (instead of an extra cb in 352) to drop back once in a while to help moving the ball closer to opposition penalty area where the two remaining forwards await.
352 might be good to soak the pressure but it's no where near good for possession football. Inevitably a team ends up playing with 5 defenders.
3-something-something would make sense for us when our midfielders are in useless form.
conte switched to 3-5-2 because he wanted to field his best players: bbc + mvp determined the formation. the same could go to current juve too: it's hard to bench either of mdl, bonbon and chiellini, and we can barely field 3 in-form cm's, so i'd try 3-4-3 with only 2 cm's, mds + sandro as wingbacks, plus this weekend's attacking trio. even a 3-5-2 with cuadrado and sandro as wingbacks, and dybala+cr up front could look solid.
anyway, if sarri can keep the 4-3-3 working with cuadrado, i'm fine with that, too. just don't play pjanic until he's fine again, and don't overuse bonucci.
