NO. Try necro if you wish to get it. You won't like it.

If you want to see companion reactivity at its fullest, take necromancer specialization. The only companion who doesn't give you grief or outright disapproval is Cassandra. With Blackwall, it's a full disapprove too, not just slight. It wouldn't be so bad taking the MULTIPLE approval hits, yes, there's more than one for at least one companion (probably Sera), but I was so infuriated by not being warned ahead of time, I wasn't really paying attention to who was saying what. The ideal time for a warning would be BEFORE I scouted the Exalted Plains, locking the level so low that by the time I finished dealing with Hawke, I wasn't even getting XP for some of the baddies. If I'd been a KE or rift mage, I'd have everything I needed before I even got to Skyhold. Then I'd be able to get access to more than one decent spell, have it available from the beginning, and have a usable focus talent. Oh, and if you like a balanced party, the only mage companion who isn't insufferable is always going to be a duplication of talents.
I will never again waste my time choosing necromancy as a specialization. I feel cheated of the time I spent developing the character, since except for walking bomb, the skill tree is only marginally less useful than the level 2 talent energy barrage. I think players who choose necromancy need to be given the option to change their mind, or specialization. And an apology. I think an amulet or something from one of the shops, like that mystery shop in VR. If the item (1 power, 1 perk, 1 level, isn't it) is worth 10000, I think 30000 would be fair. If it was available, I'd buy it.
