In general, as I understand it, the robber is positioned not as something stealthy, but as a fighter who plays from evasion in a duel. True, I have not tried to play like that yet, in my understanding, stealth is more important, you are a scout, you are a saboteur, especially if you want to play a shinobi. But the robber is a fighter who builds his build based on endurance. Each class is tied to its own characteristic.
