92 is more than enough for anything I would do honestly, hell 75 would be perfect for me as well. Currently on live I hit 110 I want to say, but I haven’t attempted further, and even that attempt was smooth, albeit a bit slower, similar to your 4-5 casts of bloodwave. I have no mythics either. I’m rather surprised by this to be honest. Now I think current Bloodwave can get upwards of 120 maybe even higher on live at the moment?
So being reduced to 92, with all the nerfs to it, and the increase is difficulty I see as a win for that build. Will it be the best build for necros going into S8? Probably not, but it’s good to know, at least right now, it’s viable.
