Hi! Because I like to think logically and in perspective, I have some questions about the choice of Incanter's Absorption talent for Arcane Mage.
So if I have to analyze this talent:
If we speak for encounter where there is no Fire or Frost spell AOE damage (where we can use Frost or Fire Ward to proc this talent) the only way to proc this talent is Mana Shield. So:
1. 1330 damage absorption = average 200 SP for 10 sec (in case all Mana Shield is absorbed by one hit).
2. draining 1.5m per point absorbed = 1995 mana + 221 mana (the cost of the Mana Shield spell) = 2216 mana lost for each time using of Mana Shield spell.
3. The use of Mana Shield very often will drop the longevity of Arcane Mage's mana very fast.
So my question is if you don't use this only for burst, why actually you need this talent? I perfectly know that Arcane Mage really suffer by mana loosing and here we can speak about throughput vs longevity. I know arcane mage is not healer spec and hardly we can speak about longevity for dps but the mana management is really important for Arcane Mage. I had to watch some streams of Arcane Mages and I was really surprised when I saw some Arcanes on 4k mana on 50% of LDW 25hc after spended Evocation.
Second my question is: Is it better on longer fight like Lich King and lower geared Mage with not so much haste the use of 3AB (instead of 4) then AM? Cause:
1 AB = 214 mana
2 AB = 588 mana + 15% more spell damage
3 AB = 963 mana + 30% more spell damage
4 AB = 1337 mana + 45% more spell damage
AM = no mana cost cause of Missile Barrage + 60% more spell damage
1. Thoughput
The choice here is between one more AB with 45% more spell damage + AM with 60% more spell damage VS AM with 45% more spell damage but reducing each cycle with 1 additional AB => casting AM more offten
Personally I tested several times using rotation with 3 ABs and with 4 ABs and the difference between dps values was not so big. In both cases I tested with such value of haste raiting where I can be able to cast 4 ABs with 4pT10 proc.
2. Longevity
Calculating all mana required for these spells we have 3102 (with 4AB) VS 1765 mana (with 3AB) which is ~43% mana saving.
All this is because it's one to go with full BiS group raping most of the bosses for 3 minutes and completely different going with no so well geared group.
