So, some people have been wondering what kind of mileage is possible out of the Non-disc 2pc. I was curious as well, so I did maths. I did the calculations in a cleanroom, so these scenarios do not account for lag, etc.
DH now is the trigger for the 2pc, which doesn't change the fundamentals on the cost reduction, but does make it far more applicable to play style. It is unknown at this time if the 2pc will trigger for DH or not.
At the end of each section, you'll see the following results:
Savings: How much mana did the 2pc save you
Savings for 3min timespan in MP5: The savings as spread out over 3min presented as MP5
Maximum Potential Savings in MP5: The savings as spread out over 3:23, 6:23, 9:23min, etc, presented as MP5
