Magblade Question: Grothdarr or Lighting Destro???

MyKillv2.0

After the nerf to crit damage on monster sets, are they even going to be worth running after the next patch? Currently, i run Spinners and Jullianos with a Grothdarr set up. However since the monster set won't crit, the set takes a pretty big hit. I wonder if moving to a double destro from dw/destro with a front bar lighting staff would work just as well to compensate for the loss of dps from the monster set. Or if the monster set nerf would still out perform the lighting destro
