According to Simulationcraft, Arcane dps actually went up (by a nominal amount), but 3.0.8's modeled output was 5970, and 3.0.9's is 6032.

Affliction locks are still modeled above us by about 10% (if they can stand still) and 20% more on a Doomguard fight like Patch.

Rogues seem to be modeled above us as well now by about 200dps, those being the two distinctive simulation changes in 3.0.9.

@Manly, might wanna edit first post regarding new glyphs and such.

Its not the kind of thing I would forget to do. However, I don't deal with speculation and false information. I am mostly holding off to get confirmed results about what changes are in before I put something up, and possibly get it wrong, then people start repeating over misinformation (even after the fact I correct it later on).

If dedmonwakeen is checking the forums, can you let us know if your new model is with the 1 minute/10% AP or 2 minute/20% AP (since neither is confirmed yet) and which glyphs you were using that resulted in a nominal increase?

Looks like the same base rotation is factored (ABx3 -> MBAM or ABarr) keeping AP up as frequently as possible.

well, the official patchnotes say it's 20% damage/mana, cooldown reduced to 2minutes base, talented to 84 seconds.

My main's realm isn't back up yet, but a bunch of other ones are... I chose one and made a new Mage there, and looked at the talent tree. Arcane Power does, indeed say 20% and NOT 10%. I couldn't tell what the cooldown was, however. So maybe we're not as f'd as we thought?

Did you mean with glyph, or did they increase the duration on AP as well?

Does that mean you can use POM at the tail end of AP?

Couldn't you cast POM before the fight started? I could have sworn the POM and Potency buffs don't have an expiration timer, so assuming you do this 1.5 seconds before the fight begins this should work

If you are not glyphing AP you will not be able to cast POM during your first AP anyways. So instead of waiting for the 15 second AP debuff to wear out before you can use your first POM.

edit:
It's not 10 seconds.

Just for clarity, I'm guessing this is with talents and with [Glyph of Arcane Power]?

(From those of us stuck at work, thanks for the info.)

Edit, @above:

What would be the point of casting POM 1.5sec before the fight? You cannot use AP until POM has been CONSUMED. You can cast POM an hour before a fight, it's still not going to let you use AP until after POM is gone.

It does sound like we can get an AP/POM off at the tail end of a glyphed AP. Will just require more vigilance on your buff timers.

They don't have timers, but:

In other words, when you cast POM, AP will be unusable until a GCD after the POM is removed (used, dispelled, cancelled, etc).

On live, AP puts a 10 second cooldown on PoM. In addition, PoM may not be cast while AP is active. So you can either click off AP after the 10 second PoM cooldown to PoM, or wait for AP to end to PoM

Updated my post. AP locks out PoM for the duration of the AP, even though the cooldown is technically only 10 seconds. You cannot use AP/PoM together at all.

Based on the spirit behind Blizzard's PoM/AP change, that is, to lower burst damage, it made sense that casting PoM first, and THEN casting Arcane Power would defeat their purpose, even though their patch notes did not explicitly cover this scenario. Now that my realm is up, I was able to test: if you have the PoM buff on you, and you try to cast Arcane Power, the game reacts as if Arcane Power is on cooldown (it says spell is not ready, you get the sound, etc) even though it's not actually on cooldown, and my cooldown timers don't show anything.

So, at least we know that now, and it makes sense.

Out of curiosity and with respect to the model, if you have effectively cut the burst given by AP by 2/3, what is the substantive value of disallowing PoM with AP now? It's not a significant boost anymore (a trinket may likely be a bigger boost). It seems as though the fix was redundant and a new fight mechanic has been introduced without effectively addressing its stated intent.

EDIT: Additionally, with due respect to the new AP model, it seems to set a new precedent in mage play. 42-second cooldowns (with talents) for minor spellpower boosts do effectively reduce the PvP burst problem but now largely make AP an affected buff. Perhaps AP has outlived its usefulness and can be considered for the scrap heap in future releases. The DPS gain may well be more effectively applied to base spell damage or glyphs.

The next interesting question is whether or not to POM on AM or POM on 4th AB. Considering the new AM glyph of course. In one case you get 30% more crit on all AM (with 190%-ish crit multiplier), in the other case you get reduced cast time on AB and 30% more crit.

It quite obvious. Take an arcane mage in 3.0.8 with 2200 spell damage. That quite easy to reach with some pve gear and arcane mind. Now keep in mind I'm ignoring more spell damage coming from mana gem activation, and totems. Casting only the sequence "AP AB POM AB abarr" did 16000 damage non-crit. As I said, thats with no debuffs on the target and with no cooldowns other than AP and POM used. It would be more with totems and mana gem. And POM gives 30% more chance to crit to your 2nd AB too.

That would have to assume they fixed the earlier discovered bug with AM consuming potency and not benefiting from it's effect unless the original cast (of AM) proc'd it (clearcasting/potency).

Can someone please test whether or not this got resolved?

That's an interesting question. I would think that an increased crit chance on a 3stack AB buff would yield more dps if you were to crit that AB. Though if you had a MB proc it might be a good idea to use POM on glyphed AM.

I thought Potency only affects the first missle and is not carried throughout.

Potency does indeed affect the entire AM channel. The exception being a bug that was introduced (and as far as I know still active through yesterday) where potency was consumed by the AM cast but not applied to any missiles. If the AM cast proc's clearcast/potency, however, potency would be applied to each missile and then consumed when the channel ended (CC would persist to the next spell, though).

Which definitely figures into the argument of the AM glyph vs the AP or Molten Armor Glyph.

I look forward to seeing the math done if we need to switch from AB, AP, Molten/Mage Armor Glyphing.

Am I wrong, or did the AP change actually allow us a bit of a dps boost.

If it's used every 84 seconds at 20%, that means we can use it 2x every 2mins 48 seconds (resulting in 40% over 2 min 48 seconds instead of only the 30% over 2 mins).

That's a boost in the time frame of fights we're currently looking at, excluding Sarth 3drake or something.

Opening with AP & Mirror Images could even result in a potential 3rd AP being used now in fights, mana permitting of course.
