You know what Skyrim really lacks?
In Conjuration they are pitiful amount of Daedra summon there is in total
And that's it, a truly pitiful amount and now let's compare to oblivion
there is such a lack of the variety and choice
But let's give Skyrim it's best chance and add dlcs and creation club
And in that case the list goes
Golden saint warrior/archer
Dark seducer warrior/archer
Flesh Atronach ( Which while also very necromantic has a Daedra in so it counts)
Even with DLC and the creation club it's such a big downgrade, while I love being able to summon two things in Skyrim I wish the options to pick from to make full use of it.
Also I didn't mention any necromancy here because both games did it pretty well, Skyrim with actually being able to revive bodies early on and oblivion with its vast options of skeletons,zombies, ghosts and even lichs, Skyrim even adds 19 new necromantic summons (including a fucking bone Colossus, ESO sweep) with DLC and creation club and a bonewolf pet and a skeleton forge, but to be fair if I'm.count the bonewolf then I should count the manic and Demented elytra Nymphs ( wait are elytra Daedra?)
Either way my point is that simplification of the magic system in Skyrim has caused lack of depth in more ways than just mysticism being taken outback and being shot and spell-crafting with it.
So yeah more Daedra please todd
