So, I'm a big fan of pet classes in any MMO and when I saw the Daedric Summoning skill tree I was at first very excited, however in game the skills are both very dull and very weak.
there are only 3 summons in the game, the first is the unstable familiar which was so weak it took it about 10 seconds to do the equivalent of one of my regular attacks when I tested it out. it also dies very quickly. You can mutate it but it really doesnt make it much better. it's just way to weak with no special abilities.
the twilight familiar is a little tougher, but again, it is weak, it's nice that it can be built into a support type creature, i could see both the heal and mana regen being useful but I want a combat pet, not an extra source of regen.
the storm Atronach is actually very strong, my main issue with it is that it's basically an immobile turret rather than a creature. it lasts for short duration, can't move does a bunch of damage and then that's it.
The bound armor and ward are ok but the fact that all your spells limit your mana means that you won't be able to do much more than keep them active. I really am dissapointed in the summoning tree, as in skyrim I was strolling around with a daedric prince and storm atronach following me around laying waste to the country side. I don't expect to be overpowered but I would like something that at least tries to make pets/summons just a little bit interesting, you can't even control them.
