Is it true that only two of the warlock abilities are useful (even situationally)?
What does warlock allow you to do other than burst a single target (pole of agony) and do melee range sustained damage (theurge)?
I know that theurge also gives some defense as well. However, all other abilities from the class are just completely useless? I’m trying to determine whether to finish up my build with Warlock or Necro, and it seems to me that while many of necro’s skills are only situationally useful - they all have some plausible purpose.
