A four charge Arcane Blast on live does 192.4% of your spell power, multiplied by 3.88 = 746.51% SP.
Under the effects of Overpowered, this on live equates to 1269.07% SP.
A four charge Arcane Blast based on these changes will therefore do 746.51%SP*1.05 = 783.84% SP.
Under the effects of the new 60% Overpowered, this will equate to 1254.14% SP.
So (assuming I haven't gone wildly wrong with my math) we'll do just under 15%SP less damage during the 13-16 seconds while we're inside AP, but we'll deal 36%SP more for the 74-77seconds that we aren't.
For me personally:
123746*3.88=480134 (4C Blast on live)
480134*1.7=816227.8 (4C Blast using Overpowered on live)
480143*1.05=504140.7 (4C Blast with changes) --- 5% buff.
504140.7*1.6=806625.12 (4C Blast with changed using Overpowered) --- 1.2% nerf.
A four charge Arcane Missile on live does 5*(44.3% of spell power), multiplied by 3.88 = 19.4*(44.3% of spell power) = 859.42% SP.
Under the effects of Amplified, this on live equates to 5*(44.3% of spell power), multiplied by 4.48 = 22.4*(44.3% of spell power) = 992.32% SP.
A four charge Arcane Missile based on these changes will therefore do 5.25*(44.3% of spell power), multiplied by 3.88 = 20.37*(44.3% of spell power) = 902.39% SP.
Under the effects of new Amplified, this will equate to 5.25*(44.3% of spell power), multiplied by 4.36 = 22.89*(44.3% of spell power) = 1014.03% SP.
So (again, assuming I haven't gone widely wrong with my math) damage from Arcane Missiles using the new Amplified talent will actually be higher.
For me personally:
145160*3.88=563220.8 (4C Arcane Missiles on live)
145160*4.48=650316.8 (4C Arcane Missiles using Amplified on live)
3.88*(1.05*145160)=3.88*(152418)=591381.84 (4C Arcane Missiles based on changes) --- 5% buff
4.36*(1.05*145160)=4.36*(152418)=664542.48 (4C Arcane Missiles using Amplified based on changes) --- 2.19% buff
I find the math correct, but some numbers seem very odd to me. The first one that comes into mind is that you multiply for 4AC by 3.88 which means that 1 AC gives you 97% dmg bonus per charge? That is insane as I have 33% mastery and only 76% bonus dmg per charge, but we can assume a simple number mistake here or insane amount of mastery by your side.
Anyway, everything in general seems quite right to me as I got very similar results myself. Using the same build as the normal build right now with OP I see very minimal differences for AB and AM in OP
- about 10% less dmg of AB during OP (60%), but about 30% dmg buff with 4AC
- about 55% less dmg of AM during OP (60%), but about 15% dmg buff with 4AC and amplified
What I can conclude is that we should see almost no change - a bit less of a burst yet similar numbers due to the bigger numbers during conserve/mini burn phases. Therefore, I do not really see the point of this change. Maybe it will be a slight buff with the 2set bonus as we will have and use more AM during conserve/mini burn which dmg is buffed and also we will have more mini burns than conserve with the 4set bonus therefore there should be a more noticeable difference then, but that is just my speculation.
