PVPing on lockFollow

I like to add all my insta-dots, then fear and drain life.

Also, i try to stay alive =D

depends on what kind of fighting you like to do

If you like to engage in large groups of people with your own group of people, then you should just Dot everyone in sight and not worry so much about shadow bolts and immolates as you'll be running head long into a huge mess. Howl of terror and then go around drain life to stay alive

if you like to lone wolf, go fight solo 1 v 1's or something in a BG, then you might want to start with curse of tongues or curse of exhaustion based on vs mage or melee, vs hunters 1 v 1, I'd just run away. It's too much trouble and locks don't do too well vs intimidation, immune to fear, and crazy hunters vs cloth damage.

Anyways, follow that up with fear cause by that time they would have targeted you too. Then insta dots cept for agony. Then drain life, fear, death coil as needed.

Locks in bg's have a good time vs some warriors, rouges if you can spot them, mages, other locks (whoever is more skilled at fearing and resist luck), and pld's if you don't mind waiting 20 min to kill something

hard time killing resto druids, shamen if they get too close. At range, shamen are not too bad. shadow priests are so annoying and I run out of mp usually unless I had felhunter out and on them, I usually end up dying from oom vs shadow priests that know what they are doing...

hunters, just the worst, I have the toughest time vs hunters. They out range me, concussion shot is annoying, and silencing shot is just deadly. Their pets are really good at spell interrupts and I'm usually dead by the time fear goes off after like 8 seconds and sometimes that won't even matter cause they are big, glowing, red fear immune things that probably will die from your dots after you die, but they get the HK first and you'll be in the graveyard getting "insigna removed, may only spawn at GY"

My strategy in PVP is significantly different than playing the game elsewhere.
First, I keep separate gear for PVP than for playing: more emphasis on defense and agility, because spell damage/regeneration is not useful when being hit for more damage at once than I can do.
Second, I dont worry so much about survival, because resurrection is no big deal in the Battleground. With that in mind, I want to do as much damage as quickly as possible.

My combination is usually: Curse of Agony-- Corruption (improved)-- Fear-- repeat. While they are running, I'll use Drain Life or Immolate, depending on how healthy I am. When they come back at me, I'll Fear again, or use Death Coil to give me time to run or cast Fear again.
I think it all depends on what type of character I am fighting, and how many there are. That combination is usually affective against rogues and other fighter-types. For Hunters, I usually have to use Fear to keep their pet at bay.
Against other casters, I dont use Fear, but put more attention into draining their mana, silencing, and casting Shadow Bolt; use Fear or Death Coil only if they are getting an advantage, otherwise I dont need to worry.

Do not belong in the same post!!! A good lock will always use all of his resources including fear. Fear is a major roll in PvP and PvE

Just my two cents :)

if you have any skill what so ever fear should only be used in emergencys not on every single target, you just just as easily dot and searing pain the life away and save mana for the next fight instead of dragging out a 20 second fight with a rogue to a minute long fear spam.oh and soul fire ftw stupid nelf huntards never see it coming then wonder how 1300 life(still only at rank 1) just got taken out of them.

Someone wrote that damage isn't important? And I who went to read the forums here to maybe get some information, ups spanked my own fingers here I see.
Anyway. Ofc there is combinations that is better than others.

Main things to know with fear, since tbc and the new talents and stuff you can be sure that all classes can break fear at least once and some will be immune for some time, second thing is that to hig dmg will break the fear so high direct dmg spell should be avoided unless safe distance is met.
So the thing is to trick you opponent to blow their cooldowns/trinkets.
Once you have a target in fear use dots + drain life / mana. Don't use direct dmg spells, searring pain, shadowbolt/burn, incinerate, immolate.
Also a very good tool is to download a timer of anykind that warn / keeps track of your dots and fear cooldowns etc.

For burst dmg destruction build, you should enter a fight from distance and before the opponent is on you you should have killed him allready. Here daze is the trick. immolate, incinerate, conflagerate. shadowburn, Shadowfury + granades, immolate, incinerate, conflagerate
With enough crit you should be able o dish at least 20k dmg before they even reach you. ( this if you start the battle), as soon as a melee get's on you daze them deathcoil or whatever you can to get them of you.

With felguard it's a complete different thing, dot up, felguard them and run at safe distance away from them keep them chasing you while you dot them over and over again.

My point, sicne tbc fear is not to be trusted best use for it is to gain distance and buy a short amount of time, not saying it shouldn't be used only that dmg +stamina + ressiliance > all. not def + agi?, you going o outlast a warrior fat chance. you have to kill them before they kill you thats what pvp is about killing things.

Fear is fine, get all your dots on them, drain some life, you can even cast a shadowbolt sometimes. If it breaks fear, who cares, you still got a free shadowbolt off, and all your dots are ticking. If mine crits, thats 3k right there, with dots going, and I drained life back so I'm probably at 80% while they're at 40%.

I suck at PvP. This is mostly because I don't fear enough. The fact of the matter is, it's an awesome tool and if I could keep up with the 10 things going on at once in an arena I would be fear juggling people like I did with mobs. Why? Because it isn't about how you play the game. It's about winning.
