Why This Route Works
High Velocity Rounds gives this build a clear first job. A good POE2 starter route should be easy to diagnose: one main action, a small number of support tools, and upgrades that reinforce the same character direction.
Armour Piercing Rounds, Flash Grenade support the route when a specific problem appears. Add them for coverage, safety, or tougher enemies instead of filling the skill bar with overlapping jobs.
The best decision is not whether the build is perfect on paper. The useful question is whether it matches how you want to play, how much complexity you want to manage, and what problem your current character needs to solve next.
