Personally, I would like to see that returned in some way. Or, maybe instead of Branching Core attributes (As discussed earlier by someone else, and sorry but yes it would make the system waaaay too labyrinthine to be worth the time it would take to balance it all) Maybe branching Skyrim attributes... Select Magicka, Select Spell resistance. Select health, select HP. Select health, select carrying capacity.
To an extent this WAS added in through the perk tree... but sometime some of the perks don't have the greatest reasoning behind the justification of placing them under the purview of one skill or another. Why is Unarmed combat kind of restricted to heavy armor when you really don't want 10 tons of armor holding you down in a fist fight? Why can the only way I can gain telescopic vision via the Bow skill and not a magic skill?
And, weapon damage should be less than it is now, with a greater level of customization: Maybe I want to do bleeding damage with knives instead of JUST axes?
Your choices are more meaningful but you also are limited to the number of choices allowed... Which is one way of doing it, personally I don't like it.
I also think a greater focus on the number of skills and larger perk trees could have made everyone happy.
Mind you I don't find any of this bad enough that I wouldn't play... I think perk trees work pretty well and that the removal of attributes makes playing much more efficient. Still... I would have liked to have seen MORE perks with More skills with More options on the directions I can head with the options I have made.
But the thing is, it's NOT less choice.
Because you couldn't choose to do bleeding damage with ANY weapon in previous games. So the fact that you can specialize in different weapons, and get different types of damage through it actually -IS- more meaningful choice than we had before. Daggers never had any type of specialty to them before, and now, they do! That's more choice, that's more -meaningful- choice.
I'm not going to argue whether or not certain perk placements make sense or not. All I'm going to say is, a perk being in a logical place or not is not a lack of customization or depth, it's a subjective preference on how that depth is implemented.
The fact is, every effect that came from Attributes (except Speed, which -has- been removed for better or worse) is in the game as either 1.) perks or 2.) the remaining Attributes of Health, Magicka, and Stamima.
I don't think that Attributes allowed for greater customization than perks in the least bit. I am not inherently against Attributes, I did not take issue with having Attributes in Morrowind or Oblivion, if they came back for Elder Scrolls VI I wouldn't be particularly pissed about it, and while there were obviously some "efficient" leveling methods (Oblivion being the worst offender), I didn't find Attributes overly deep, complex, nor confusing. I believe that perks are a better way of going about said customization, I believe it offers -more- than Attributes ever could. I didn't feel like Attributes ever added anything unique to my character, where I feel that perks do.
