While I understand it may actually be your personal feature to not react fast enough, I don't think 200-300ms delay is all THAT bad.It frustrates me you're having troubles with our dragon babe. You mentioned having tried different classes, but how did you use them? First of all, if you have a thief AND Heart of Thorns, I would totally recommend you trying to do catch as a Daredevil with dash evade skill, and also using a staff for Vault. While you may dash too far out of the circle, Vault is a very precise skill with just enough range to make it.Now IF you have no access to what I mentioned above, do try an engineer, those guys have a lot of endurance regen and a trait for 25% movement speed constantly.Another possibly helpful option is warrior for the variety of movement skills. Also, it's a good decision of ANet to not make the ball blockable or avoidable like many similar things in openworld. I really do hope for you and your Skyscale friend to learn to catch <3
