I admit, I don't know much about destro warlocks. However, I feel that the class can be incredibly powerful under the right circumstance. For destro, it is all about how much damage you can put out in the shortest amount of time possible. You won't have much surviviability, and that is the classes downfall. Thus, I have decided to make a destro spec that tries for more survivability. Since there is no innate shadow damage resistance shield, I will focus on my ideas for this first.

This spec gives you not only the benefit of nether protection (the win against other warlocks) but also gives you most of the traits down demo that will increase your mana and survivability (more life). I am a huge fan of demonic aegis, it is unparalleled when paired w/ any life gain effects. I chose not to take improved life tap since your life will be the deciding factor, not your mana. Corruption is a must as far as I am concerned, insta-cast dot that does a crap load of damage is amazing. This spec you will ALWAYS first put curse of shadows on your target for the extra damage you will get. One thing to note: Aftermath is exceptional when it procs against non-ms warrior targets. It even procs off of hellfire.

This spec does have some problems though. Your fire spells aren't really being beefed up, thus you rely completely and utterly on your shadow damage. In addition, you don't have max damage for your shadowbolts (the 0/21/40 spec is the most powerful for that). You are incredibly reliant on your crits for damage too (ruin = the win except on people w/ a lot of resilience as almost all pvpers now have). However with good spell damage you can overcome the reliance on your crit damage issue.

Thank you so much for working on this! Man, its a hard decision, which way to go, as a lock! I have already respec'd, 7/7/47, so we'll see how that works!
I do really like your tree too...hmm... decisions, decisions...I'll get back to you on this, lol! Thanks again!!! So much!!!

Destruction is a tricky talent tree and I have little experience using it in practice so pretty much everything I have to say is theory-craft rather than something derived from experience.

Sacrifice based destro builds at the moment seem to be the most potent option for damage for the aspiring destructionist (destructionado? maybe just destroyer). Though designed for pve, they do enough damage to be useful in pvp as well. These builds can be fire or shadow based.

Fire You might want to switch the tier 1 talents if you never use SB.

Shadow This gives you more of the nifty destro talents since you free up a lot of +fire dmg type of talents. With this build take cataclysm if you do more pve and aftermath if you do more pvp.

I am not a fan of shadow fury. It takes a ridiculous amount of mana, does not do that much damage relatively, and has a cast time (albeit an itty bitty one). Sacrifice gives you much more versatility and much, much more damage. And you are already going a reasonable distance down demo. This does require that you give up instant corruption, which is unfortunate since this transmogrifies this from a shitty spell to a very good one. One thing to note about destruction warlocks though is that they do not rely on dots. Destruction warlocks (well, non-sacrifice builds anyway) often benefit from burst/CC damage cycles using the succubus to seduce. Dots prevent seduction or at least break it. The warlock fears/seduces, applies burst damage (ie: immolate > incinerate > conflag or SB > SB > SB), and then re-seduces. She does not use any Dots, but just applies curse of shadows or elements.

I could pass on aftermath. It's nice but if you need talent points elsewhere I would not hesitate to drain them from here. Same goes for souleech. In pvp a 30% chance to get 20% of health back is nice but I see destro as more about forcing as much damage as quickly as possible at the expense of survivability. I would have to actually use this talent and geta feel for it before I passed lasting judgement on it however. Finally, I do not think it is worth it to put any points in improving immolate if you are not going to at least get conflagrate or emberstone. If you are leaning towards fire damage, however, it is very potent with the aforementioned talents.

Well, I officially do not care for Destruction at this point. It drains my mana so fast! I'm just going in circles...What the hell, on to Affliction it is. I'm bound to decide which of the three I prefer pretty soon anyway! :/
