It's not the 30% from GB that gives it the increase; it's the fact that you need all these buffs up prior to shooting out Wildfire to maximize DPS during the 15 seconds so it gives you the extra 25% explosion on the end of the Wildfire proc. I don't parse and I haven't tested not clipping them but this gives you insane burst at the beginning of the fight and everytime your CDs are up. Like I said, at level 57 with outdated gear, my Wildfires were consistently around 3k on bosses while my Split Shot was hitting for less than 600.
I can tell you that I steal enmity from the tank if they aren't on top of their enmity game at the beginning of a fight because of this, though. I'm also consistently above BLM on the enmity bar for the first minute of a fight after this rotation, but I don't know if that's from them using Quelling Strikes and me not using it.
