Seeing that the nerf aside from lowering the combustion damage is around 5-6% in dps and even before 5.1 if you know what you were doing in lfr you had good 20-40k dps lead on other people.. its not really a great benchmark. Anyways thing is we all expected to see the nerf incoming, but this was just too soon.. 5.2 aint even near.. so ye, the choice is: roll arcane or dont exept yourself to top damage anymore if your dps is competitive and equally geared
