Seems like everyone wants good CC, but no one wants to do anything. Since Stormchasing was so kind to try and help, you should all pay more attention. I don't have any 85 warlock yet, but I'll try a few suggestions and links.
"Unstable Affliction:
Use this spell to cover your dots from dispels and your Fear! Best way to do this against team that's good dispelling Fears is cast UA + Fear. Often when they see the fear land they will start spamming dispel, there's a good chance they will dispel the UA.
Of course People with alteast half of a brain wont dispell it
Haunt:
Keep this spell on CD all time, it's free heal, small burst and buffs your dots.
Howl of Terror:
Try to use this spell only when you have atleast two enemies in range for it, but if it feels impossible to Fear someone use it to get him off you.
Deathcoil:
Defencive:
Use this spell as your last resort CC to save you or your buddy from nuke, or in locking down enemy healer.
Aggressive:
If your going for fear lockdown kill and the healer being CCed has almost fear off him and you think you wont be abel to fear him fast enugh to stop the instant heals send a deathcoil to say "go away". either you will kill your DPS target or it gives you enugh time to cast a new fear
Fel armor & Demon armor
Rotate this armors, if they aren't attacking you there's no sense having Demon Armor on. Pop out Fel Armor for extra damage. However if they focus damage on you, have Demon armor on if needed."
Teleporting could be really tricky for a bot, but if you want to try that too, I'll add more info.
Basicly
-Start off with unstable affliction
-Keep eye on your dot timers
-Use that fear to control them
-Multitarget damage (Soulswap = Love)
Ps. Dont forget damage break fear

how ever UA is needed to protect fear
