A free speedhack script for Crystal of Atlan has been released for the Speeder Scanner. It can increase your attack and movement speed by an unlimited amount. I believe the attack speed hack only works in story and solo missions, but I could be wrong. The movement speed hack should work everywhere.
You can find the Speeder Scanner here.
You can find the Crystal of Atlan speedhack script in Launcher's Marketplace. The instructions for using it are included with the script.
