I have tried playing a ninjas/dark MM since the patch

Only level 9 so far.  But I joined a team of 8 and my ninja did not immediately die.

 

I consider this an absolute win.

I think I once back on live described Necro/Poison as a slog through waist deep mud while dragging my minions behind me.  Whatever they did to these sets it's nothing like that now.  Might be a bit over-tuned frankly, but it's probably on par with a good performing Brute or Scrapper toon of the same level.  Lots of fun to play.  Plus insane team debuffs.
