I just signed up to discuss a little bit and give my point of view. If I'm wrong, please tell me.
First a few punctualizations. Maybe they can help someone:
-As you say, the main stat after intellect and hit cap is still Mastery. As long as you keep your mana over 70% your DPS will be higher than with haste.
-Haste increases the mana regeneration so that everything remains the same way but faster
, I mean, if you can cast AB 15 times in 30 seconds in which mana has regenerated arround 50%, when your haste level allows you to cast the same 15 AB in 20 seconds, mana will have regenerated also 50%.
And now the discussion. Rotation for me goes like this:
-Keep Nether tempest / Living bomb / Frost bomb alive
-AB spam: Spam Arcane Blast until you have 6 arcane charges. Use 1 arcane missiles during AB spam only if you have acumulated two of them
, and have three or more arcane charges
-Use all the arcane missiles you have when you reach 6 arcane charges
-Use arcane barrage.
-If mana is under 85%
when starting a rotation, use the former steps with 5 or 4 arcane charges instead of 6 or use a mana gem to mantain mastery bonus high.
Let me explain:
During the AB 1, 2, and 3 mana regenerates up to 100% (or almost). It's a waste to use the missiles here, as damage is still to low and they won't help regenerating mana. after No.3 mana won't reach 100%, so you can use arcane missiles to let it regenerate, but keep at least 1 for the end, because AM damage is bigger than AB, and will increase your DPS, and also will regenerate mana for the final strike. If you have two of them in this moment, and mana reaches 100% you'll achieve maximum rotation damage.
Please, try and tell me what you think.
Note that Nether tempest / Living bomb / Frost bomb also procs arcane missiles, so if possible, try to use it just before Arcane barrage and if it procs AM, use them and then release Arcane barrage.
