My guild got past Spirit Kings (YAY - thanks to those of you that posted in my other thread, the info was very helpful).
We started to work on Heroic Will last night. I was arcane and I just feel like the aoe is lacking. I don't have any logs, I believe our RL forgot to run them.
I swapped to frost even with my arcane mastery reforges and it seems like I got better dps and added more aoe. However, my RL asked if I considered going fire for this. I told him no, I just don't feel fire is going to be better than the arc/frost on this. He suggested fire for Spirit Kings and I tried it for a night and while I know how to play fire, even with just under 30% crit, RNG was hating me. Fire aoe just doesn't feel great to me either.
So, those of you that are working on Heroic Will or have killed Heroic Will - what spec do you prefer and why?
