If you only have one tic, such as with CoD, faster dot tick is the same as shorter duration. Although I suppose with a huge amount of haste you would get 2 ticks out of it in 1 minute?

When I read the description of the talent change, it brought to mind the Elemental Shaman set bonus which reduced the cooldown on Elemental Mastery by a couple seconds after spell casts. The description of Impending Doom seemed like it would function in a similar manner.

My point was basically once you've reduced the cooldown on BoD by 1-2 seconds, anything beyond that isn't really useful unless you have multiple targets to DoT.

That's mostly true. The main advantage from Doom's perspective is greater flexibility, so you'll have more opportunity to renew the spell at a time that doesn't impact your rotation.

I've gotten so accustomed to the current dot mechanics that I don't really think anymore about how counterintuitive they have gotten, and I'm really excited to see such a shift in our basic playstyle. Unless I'm understanding things wrong, the changes will require recasting/refreshing dots shortly before they fall off, as opposed to the current need to refresh immediately after the dot's final tick. I think this will make the warlock class, particularly affliction, a lot more "approachable" to newer players without necessarily becoming any easier to play.

One of the things I see that could use some clarification is whether BoA will use the same increasing damage mechanic that CoA currently does. If thats the case, will the damage of the hasted ticks be calculated over the duration of the dot (ticks in the first 8 seconds small, next 8 medium, last 8 large) or ramp up quickly and remain at maximum level for the remainder (first 4 ticks small, next 4 medium, rest of duration large)? On top of that, will an early refresh reset the dot to its small ticks or allow the remaining big ones to tick off?

The PVP and PVE ramifications of the idea of stacking DoT durations indefinitely are a sign of it being too good to be true.

BTW - the new edited info about Hellfire being meant as Demo's SoC/RoF is worrying, because it requires being in melee...

It seems like they'll have to give demo some threat reduction for at least AoE situations (if not accross the board). AoE in melee range is a lot riskier in general with the lower aggro threshold, and emphasizing hellfire will pretty much make it manadatory to do so.

More like Blizzard has noticed that Demo locks like to Meta-Immoaura and stand in there. So why not make it so Hellfire works for them? If it is dangerous, I'm sure Seed and RoF aren't going to be exclusive, so you can use them when needed. If the three AoEs are going to be exclusive, then yes, worrisome. But since there was some comment about Elemental Shamans dropping Magma and the totem being teleported or some such to the target, I would think they know that meleerange is a good option, but never a good requirement for casters.

It's going to be the same as Everlasting Affliction is now. You can't spam refresh it and increase the duration.

That is the way I read it as well. When you recast the DoT it goes back to its original starting timer kind of like glyphed Pestilence does with diseases.

For those wondering if imp's new DoT will help Affl's Drain Soul, I doubt it. Soul Siphon increases the damage done by Drain Soul by "your Affliction effects on the target". The Imp's DoT will probably be located in the "Demon" portion of the spell book, meaning it is not an Affliction effect, so it should not improve DS damage.

On a largely untouched subject of the changes, I am interested in seeing the CD on Fel Flame. If Fel Flame's CD is lower than the CD of Immolate (untalented) or UA, it will be "Haunt 2.0". Keeping Glyph of Conflagrate (BTW: is the Wowhead item linking broken atm?), immolate will only fall off after the duration expires. If you can FF Immolate before it expires every time, then it'll function much the same way corruption currently functions. It wouldn't change destro's rotation too much, but swapping an instant for Immo's small cast time would really make the spec more mobile (huzzah for GCD-running).

For the reason above, I feel FF will be on a long CD, probably longer than the duration of UA and untalented Immolate (>15sec), but shorter than Molten Core 3/3 spec'd Immolate (<24sec). The ramifications of permanently, instantly being able to refresh UA in PVP are too large for Fel Flame to have a CD less than 15sec.

Most of the lock changes are PVP-oriented. Yes, there is the very welcome change of being able to DPS and CoElements for PVE, but isn't being able to BoAgony + CoExhaustion just as alluring?

Can FoL HoT crit? I don't think it can, and I don't think Holydins are based on HoTing enough for Blizzard to implement the "HoTs now natively benefit from crit/haste" like they did for locks/priests. You'll notice that Shammies, with riptide, were not given the HoT clause. Now, I expect Resto druids to get that clause (assuming their HoTs cannot already crit). In a typical encounter, they throw out more HoTs than any other class I know of throws HoTs or DoTs, making them PRIME candidates for this buff. Assuming your raid doesn't have a resto druid tho, I imagine affl locks will trade DIs much the same way mages trade FM.

Tuberqlosis, Fel Flame was specifically mentioned to be a Demo tool. It isn't unreasonable to expect that tree to lower the cooldown to fit with Immolate one way or another, likely with Molten Core. I would find that to be a cool way to make the spell good for all more or less, but an integral part of one spec. I can easily imagine Affs going to pop Fel Flame to keep UA running as much as possible.

Also, the desription doesn't mention HoTs, while that is a logical conclusion. If it applies to all heals, then it is certainly good enough for any healer. Would be interesting if both it and Focus Magic would stack on one player. But I tought the most common target would be other Warlocks, Affs in particular. Two Afflocks doing what many Mages do already, and Rogues for that matter. But Spriests certainly make for excellent targets too.

Cangiz, your confusion is understandable, but it is really simple.

Corruption has a duration of 18 seconds. If it gets Hasted enough to get another tick in that time it will get that tick. If it is slightly lower than that it will still last 18 seconds, but the last 2 seconds+ will not actually do any damage. Basically DoTs and HoTs that are affected don't need to end on a tick.
Lets say you manually apply Corruption during the 'dead time' near the end, then the 'first' tick will happen at the time it should had the first application been extended. In a sense you can get a tick almost right away if your Haste is nearing an addition of a new tick. This should lower the 'need' to get Haste plateaus as if you apply the DoTs/Hots correctly you will not lose any ticks at any point due to Haste not addint new ticks yet.
