Ranger deep? Am I playing the same game as you? Ranger is auto attack -> AFK. Necromancer is pretty much similar, but gotta make sure to keep #2, #5 and Epidemic on cooldown! That's 4 skills, let's hope how deep it is isn't too much. And don't bring your Death Shroud bullshit, it's a terrible skill that is purely survival. It's primary offensive use with Warriors/Guardian group is Fury & Condition Removal.
Once again, the fudge you on about?
I do agree with you on some points, but you're a terrible Necromancer if you seriously believe that a good skill rotation for them consists of only 3 skills. That's only mildly true for scepter necromancers, and completely untrue for mainhand axe/dagger necromancers.
And Death Shroud "bullshit" is only "purely survival" if you go full-on Conditionmancer, and even then it has nuanced offensive and defensive uses.
I don't want to start an argument but your misunderstandings of the class are particularly egregious.
