Don't ask "has anyone done the math on ____". Read and search, if you see the math then congratulations. If you don't then no one has and feel free to take a stab at it. But asking has anyone done the math is nothing more than saying would someone please do the math for me.
Regarding the upcoming hunter changes in 4.3.2 and having played MM since the SV nerf at the start of cataclym with my alt hunter and being SV again: will the changed BA, same overall damage but 20 sec duration instead of 15 and ticking every 2 sec instead of 3, effectively increasing the DPET by one third and doubling the amount of ticks from 5 to 10, be better than immolation trap on single targets? Has anyone done a short analysis of it?
