Speccing a Warlock
Q: How does the mana regeneration portion of Improved Drain Soul work?
A: You or your pet have to get the killing blow in order for it to proc. If anybody in your group/raid gets the kill, no Improved Drain Soul proc for you. You have to finish the mob while channeling Drain Soul, meaning that you're probably going to be relying either on a nuke that flying towards the mob or DoT's to benefit from Improved Drain Soul.
Q: Do Shadow Mastery, Master Demonology, and Demonic Sacrifice apply AFTER or BEFORE +dmg gear?
A: All of them apply AFTER gear on most spells. This was confirmed by some calculations, made by Psy.

Thanks to Psy for the data and calculations.
Q: Devestation does not show up for crit chance on my character pane. Is it broken?
A: No. The reason Devestation doesn't show up is because it is tree specific. Demonic Tactics and Backlash show up because they are NOT tree specific. The Mage talent, Critical Mass shows up on the tooltip, because it is ELEMENT specific instead of tree specific.
Q: How does Suppression work?
A: It counts as straight +hit% for your Affliction spells. For more information concerning +hit, please see Shadowbolt's raiding guide.
Q: Does Improved Life Tap also increase the cost in health?
A: No. +dmg will increase the amount of health used, but the talent only increases the mana return.
Q: What's with the single point in Shadow Embrace that so many Warlocks have?
A: 1/5 Shadow Embrace is taken for a couple of reasons. It counts as an Affliction effect; this grants an additional 5% to Drain Life from Soul Siphon. It also counts as a magical debuff. This means it helps protect your more important DoT's/debuffs from dispels by counting as a dispel effect.
Q: Is Pyroclasm broken?
A: No. You don't get 26% chance to stun per TICK or Hellfire/Rain of Fire, but instead you get that chance over the course of the entire spell. This means you have a 26% chance to proc the stun per cast of Hellfire - a very small stun chance per tick. Just skip Pyroclasm; it sucks.
Q: How much +Damage does Demonic Knowledge give at level 70? And which pet gives the most damage?
A: The average Warlock gets about +125 damage from Demonic Knowledge. The Imp gives the most damage, thanks to Blood Pact.
Q: Does Nether Protection proc from Hellfire ticks?
A: As far as I know, it doesn't. However, if you proc NP during or prior to a Hellfire, you will be immune to the ticks for four seconds.
Q: What's so good about Dark Pact?
A: It removes downtime when you're drain tanking. You don't need your pets to cast while grinding unless you're using a VW (which you shouldn't be if you're drain tanking). The Imp and Succubus have very high mana regeneration rates. Dark Pact allows you to take advantage of their mana regeneration by transferring their mana to your mana pool.
