Like I said, a buff is a buff and as far as that's concerned, I'm content.
But the core issue is that 3.X rotation still beats out the new 4.0 one.
I, for one, am very interested in the numbers your friends have and would like to see them if possible.
I want to make sure I didn't overlook anything...
(I can get you RyeMinx's numbers if he doesn't reply to you, btw)
Add Foul to both UI cycles and that becomes 152 VS 149 pps, favouring the 3.X one. If the base MP buff (and the no MP Foul) allow for the 3.X rotation to get one more Fire IV, then the 3.X rotation yields around 155 pps.
