Velocity is a good metric if used in right place. Knowing how much work your team can do within a sprint is important to do predictions for planning activities.
But if you ask me "can we use velocity to evaluate individual performance?" my answer would be "No". It is a team metrics. You can use it to see what are the growth trends and predictability %.
And in no case compare the velocities of different teams.
If you observe issues in stabilizing the velocity, do not start with tracking individual ones. Deep dive into the work process. You might inspect some strange behaviors not related to the velocity itself.
The root-cause might need you to take actions on other aspects of the team work.
