A sensible starting point is the equipment you actually use. If you have a favorite weapon or a build that handles most of your endgame activities, progressing with those items gives you benefits that are immediately relevant. There is little reason to prioritize equipment sitting permanently in your stash just because it contributes to the overall system.
Resources are another consideration. Expertise progression can become expensive, especially when combined with recalibration and optimization. Players should avoid spending everything on marginal improvements while important parts of their main builds still need work. Establishing priorities prevents a situation where you have upgraded several secondary items but lack the materials to improve something you use every day.
The system also naturally rewards long-term play. Running different activities, experimenting with equipment, and collecting resources can gradually move progression forward without making Expertise the sole purpose of every session. This is often a more enjoyable approach than treating it as another mandatory grind.
For players who want to accelerate particular parts of their character development, Dving covers various The Division 2 progression options, including assistance related to Expertise and other endgame goals. This can be worth looking into when the time required for repetitive progression is the main obstacle rather than the difficulty of the content itself.
Expertise is ultimately about incremental improvement. It won't transform a poorly designed loadout into a great one, and it shouldn't replace learning how a build works. Get the fundamentals right first, invest in the equipment you genuinely use, and allow the broader progression to develop around your normal gameplay.
