As others have said, droid CC'ing the claw is one way as is "just avoiding damage". Another suggestion is to have the tank target the droid and taunt it to attack him. Of course, you have to be a decent (not great) tank to handle it... But as a tank, my role is to protect the party from as much damage as i can. So, if i have the claw on me and im running in circles around the two bots that spawn, im not putting out a perfect damage rotation. However, Directive 7 is not any where near being more then what two tionese or better geared DPS'ers can handle... Much better to have it on me then the healer who may not be able to properly do his job when he cant stand still.
Or AoE taunt I have a trouble sometimes targeting the Claw but AoET works everytime
