I gotta be honest it really feels like your options are bone spear or pick a different class.
In the betas necro had a few different builds that all felt pretty good and fun to use, but now they all got nerfed into the ground (some without being mentioned in any patch notes) other than bone spear.
I really hate bone spear.
Currently I’m using blight plus corpse blight plus reapers and bone golem (taunt, so everyone goes in the middle of the corpse explosion spam) and seems quite strong.
There are lots of builds usable in T2, but we’ll see in T4
