Ok, let me see, adressing these ones.
I was satisfied and pleasantly surprised by the perks in the game, no real complaints.
I personally think they should have had more perks to choose from, which could either be done by adding more trees or specializing the trees even more. This would let you complete less trees and make every character even more unique.
I like the fact that you don't need to plan as much, especially compared to vanilla oblivion where an unplanned character would end up spending forever in combat and kinda weak overall.
Hmmm, this is a hard one, pasts of the enjoyment of say Morrowind, comes from becoming Godlike, however, I don't think Perks in and of themselves should make you good at everything. But I think you should be able to become a pretty powerful allrounder.
I would like more perks that add different skills or abilities, utitility perks or whatever one should call them. A damage boost is cool and all, but I feel like that could be implemented into the increasing of a base skill.
I think perks should make characters feel different, so every playthrough can feel new and unique, this would of course unlock different play styles as you make different combinations of perks.
I think perks should make some difference, but I don't think the game should revolve around getting all the perks.
I think the amounts of perks should be somewhat limited, down to at least maybe 50%, I don't know, maybe even less.
I think the lack of useful perks in some situations are great, you get a challenge, and you might want to go back there with a different character some other time and try it in a different way. However, I don't think anything should be impossible because you are lacking a perk.
I think a characters power should be as a basis, character skills and perks, obviously combined with player skill to make it good, a good statline won't always save you.
Vampirism and Lychanthropy should contribute to power, but not as much, and should also have enough pros and cons that not being one has it's benefits as well.
Well, that's the longest post I've made in a while.
