All of the complaints about frostbolt damage being so low having bad gameplay feel make me chuckle since fireball has even lower DPET than frostbolt.
This pyro change was entirely the wrong direction and pushes fire further into the same situation as frost (horrible dps during filler, with occassional burst), just with still lower average dps through the entire tier. Fire has always been an RNG spec, but loading all of our damage into pyroblasts will make our fight-to-fight dps variation higher than it has been in our history, even including the 100% combustion ridiculousness.
The correct change would've been to revert the idiotic level 90 changes entirely. Maybe add a little more to fireball and less to pyroblast. I don't know what Blizzard is thinking. Meanwhile, warlocks got a blanket 8% buff across the board pretty much. I can only hope they haven't even started to look at mages yet and this was just someone's quick 2-minute bandaid because they heard there was an issue and maybe this'll shut us up.
