Fair. Alright then that must mean you think Grievous is Sidious level in speed. 🙂
Grievous was able to break through Kenobi's defenses with the speed of his assault
Kenobi has a better defense then Anakin.
Therefore if Sidious couldn't break through Anakin's defenses with the speed of his assault Grievous should logically be faster then Sidious.
That the stance you're taking here?
