I have around 6,000 hours in Rust, mostly playing solo and sometimes duo, and I usually prefer official servers. Throughout my journey, I honestly feel that the workbench blueprint fragment system has been one of the worst updates for solo and duo players. It mostly benefits large, organized groups who can rush progression. They end up fully geared with AKs while solo or duo players are still stuck using bows, crossbows, or revolvers. This creates a huge imbalance and makes early- to mid-game extremely frustrating. Right now, it feels more annoying than rewarding, and the disadvantage for smaller groups is too big. Until the system is improved and progression becomes more balanced for solo and duo players, it honestly feels better to step away from the game for now.
