There's your problem. You're playing on master, you dork... don't expect everything to be a pleasant stroll through the park. Also, it doesn't make you cool -- so cut it out with the elitist approach. What matters is having fun. If you have fun on Master, great, but don't whine about having a hard time.
Being an elitist and a dork is good. When an elitist and a dork writes a forum post, the post is coherent, makes sense, and is a reference to previous posts. When a non-elitist non-dork writes a forum post, it's a non-sequitur, internally contradicting, and nonsense post.
This thread isn't about Master being difficult, it's about Necromancy being useless (examples are right there in the first post). I cannot play on Adept difficulty for a simple reason that game is super-turbo easy and I have been nerfing myself heavily as is (not using Smithing and Enchanting at all for instance, not even using a follower, even not using sneak perks..). This isn't about elitism; if someone can enjoy Adept difficult that's great. But I don't enjoy Dragonborn egomania where my character is immortal and one-shooting everyone while in berserker mode and there is no tension and fear of actually dying.
As for Necromancy, I didn't even expect it to be superb. But I'm doing Battle for Whiterun and can't even raise a corpse? Lockpicking is the most useless tree but at least when you put points into Lockpicking you're able to do what perk is supposed to do.
I'll give another example: Fists of Steel. Is unarmed combat equal to swords n stuff? No. But it's viable. When I fight with fists, I still do reasonable damage, all the time. It's not like I pass through a door and "oh crap, my fists disappeared I need to steal new ones from dead body.. of course, that means killing someone with something else, bummer".. and then I go on a quest and "ooops, this is cannot-use-fists quest", again, bummer. Then I travel fast through the canyon and "uh huh, my fists got lost somewhere in the wilderness behind me, maybe I should wait till they find me". Or "damn I didn't kill any enemy last minute, my fists disappeared!".
My point is that someone who wants to use Necromancy will waste 4-8 perks in Conjuring tree. That's a lot of points. With that many points in Smithing or Enchanting or Alchemy or Sneaking etc, you're superhuman.
