Hmm, on our end we haven't seen any recent updates that adjusted anything significantly like that. More just the normal smaller buffs and nerfs to individual weapons. Did you check the practice range as well to see if the damage values of your weapons supported what you were feeling in-game where it was taking more shots than normal?
For cheaters, that's something every game (especially popular ones) always has to fight long-term with ebbs and flows in anti-cheat detection and successes. We've seen more reports of that recently too and are trying to work with the team to see if anything is abnormal with the number of reports, detections, or anything. So hopefully we'll find something there and help ban the latest wave.
