Hello!
Give me advice on playing as a warlock please.
1.PVE - tank, at what level you can start tanking?
2.PVP? Absolutely love pvp, want to be as efficient as possible. I like to play affli and demon. Any advice you can give would be greatly appreciated.
Thank you very much!!! 
As soon as you have Meta Rune
You don’t until Blizzard implements a less clunky version of Warlock Tanking, similar to what Mists of Pandaria had with Glyph of Demon Hunting. The current Warlock Tank sucks.
A lot of Warlock PvP is self taught. Duel people, go into Battlegrounds. Learning from personal experience is better than searching on the forums for any advice.
Also, Fear is your most powerful tool.
Happy hunting!
It’s ambiguous about PvE.
Will I be able to close dungeons and raids while tanking as a warlock?
You likely wont unlock meta until 25 due to the mobs you fight, you can get a group to carry you at an earlier level though.
Lock is good in raids but terrible in dungeon atm, this will probably be fixed with the new runes going into phase 2.
The current warlock tank isn’t as bad as they say.
It’s not going to be as faceroll as a shaman tank.
But it can easily clear any and all content in the game.
I think Immolation Aura will turn it a bit more easy mode.
Unless you have a group I wouldn’t go pre-25. Even at 25, the quest was perilous, and I had to cheese certain parts by using soul stone and yoinking items, grouping with people there, etc. (lotta high level mobs and towers to climb inside pvp alliance zones.)
Pvp it’s a boss for sure. Think drain tank cheese.
I don’t think I’ve lost a duel yet, and group PVP seems solid enough. You dont have access to fear in meta form, so if you are partial to that, you may have more fun as affliction.
Def what I’m maining P2, so I hope it isn’t too popular tbh.
The build in p2 will almost certainly be full demon, since we get soul link and magic res from fel hunter.
There is currently a little bit of debate between stacking the fire dmg from incinerate and lake of fire for TPS and dmg, over taking the mitigation runes like demonic grace or survival like master channeler. I’ve tried both and they both seem fine (at least for BFD), but we will have to see how it looks in phase 2.
Hope this helped a little.
PvP for lock is going to change fairly drastically starting tomorrow. Your pet should be felhunter, we don’t have yet. You want to spell lock healers, or other casters depending on situation.
Also depending on what your goal is for what you’re doing, you will want metamorphosis or not. For instance, if you’re playing arathi basin, and defending a node, meta might be best. You’re going to be annoying to kill. Especially if you have soul link (demonology).
There’s going to be a lot of ways to come at it. Versatility is going to be top notch starting next phase.
I personally will be going full destro/fire. And keeping fear, which you have to give up if you use metamorphosis.
Thank you!
PvP sounds awesome)
And with PvE, I’ll be patient until 25, no problem.
Technically, you get the first quest at level 20, but getting it that early you would need a couple 25s carrying you. With p2 around the corner, the easiest way would be to wait to 28-30, since you would over level the elites and be at a fair level for the level 30 demons you have to fight, making it soloable.
What’s wrong with Warlock tanks? I’ve had no issues with any in BFD…
Either as soon as you pull aggro for non intentional tanking… or as soon as you get the meta rune for intentional tanking.
For the 40 bracket you’re going to want to go down one of the trees… Destro to conflag is what I’ll play. Affliction to darkpact is next best (you don’t even really need dark pact, you just don’t really have a better option for that last point)
Demo to soul link will also work for dueling and for base sitting in arathi, but don’t expect to actually be that useful
Really though you’ll want either aff or destro at 40, specifically because you’ll want to take advantage of the increased range talents present in either of the respective trees (and by 60 you want both of those talents)… It might not seem like much, but simply being able to cast from 36 yards instead of a mere 30 will -=DRAMATICALLY=- increase your ability to survives in bg situations, as you’ll simply be out of reach from most threats.
Advice for playing a lock:
Learn your spell combos. in pvp when you’re allowed to cast you want to link a 2.5 cast travel time spell to a 1.5 cast no travel time spell, into an instant attack. The reasoning for this is that the combination of spells will all land and nearly the same exact instant, leading to HUGE burst.
Don’t just “zug dot” everything. It can get really frustrating playing with a warlock who dots everything in site constantly, as it can disrupt potentially critical CCs that would otherwise be going out. This is especially problematic with newer locks, since their dots tend to be pretty weak and making a priest immune to sheep for ~24 seconds so a greened out warlock could do all of 4% of the guy’s health every 3 seconds is pretty #feelsbad… That’s not to say that you never spread the dots around, just that you need to be smart about who and when you are dotting things.
Health IS mana for a warlock… This means while classes like mage might need to refill their mana bar drinking over 24 seconds, if a warlock is oom but full heealth, they can lifetap to even the bars out then eat and drink and be done in like 1/3rd the time.
Have 2 ranks of lifetap keybound Max rank when you need it, but 2nd highest rank for when you don’t need the massive amount. There’s no point in taking more health than required to top your mana off, and no sense in taking a huge chunk to overcap your mana.
Hellow guys!
I just got the metamorphosis rune, being level 25 (SOLO!!!) 
(my *** was on fire during quests)
I also have 84 honorable pvp victories, your tips are working!
Now I need more advice on what talents to choose for tanking up to level 40?
