I see a lot of long stories and considering what is written I wonder in some cases if you actually ever killed a hunter...

The basic story is the hunter owns a warlock by default, simply because the pet interrupts us and his ranged dps has higher instant damage then us, so lets be very clear about that

What you CAN do is try to get as close as possible, without getting into short melee range. As afflication lock (like me) I can cast everything running towards the hunter and use howl of terror (I have 1 talent in improved) so both the hunter and the pet are feared. I completly forget about the pet (maybe siphon life), cast UA and start draining, so corruption, siphonlife, agony and UA with drain will hurt him a lot and kill him anyway.

But lets face it, if the hunter can start the fight, you are dead as warlock.
Attacking the pet will make you lose so much time, that your are dead before even getting close too the hunter, remember hunters are dependant on range and there aimed shot will take (2.5 sec?) to shoot, so if you are able to interrupt it before then (deathcoil for example) that will save you 1.2k upto over 2.5k damage and buy you more time to get to him.
