Nice job Richie!
Pet now working =)
I found 4 another problems (I was playing about 25 Arena Matches with your Pro Edition):
1: Please add that Curse of the Elements is every time up on target in Arena (+ focus which is often another Enemy or Healer) and not use "Curse of Enfeeblement".
2: Please add that " Demonic Circle: Teleport " is not used automatically by ur CC... this is really retardet if you are killing target... but u can't when teleported

. If there would be a button to use by CC or by player is needed!
3: Your Pro Edition does not DOT all targets in Arena 2n2 or Arena 3n3, it doesnt matter if "Multidot" or "BG Ownage Mode" is chosen. Maybe add Soul Swap since its not removing all Dots when using in 5.4?
4: In the most matches your CC didn't try to use Unstable Affliction on target or Malefic Grasp or Haunt. Its just dotting target with Corruption and Agony and this is not enough to kill targets

(and it does not multidotting on focus or any other target.... only sometimes Corruption and Agony)
If you fix that 4 problems I guess its the best CC for Affliction Warlock then... at the moment =)
...and sorry for my bad english
