One of Skyrims greatest flaws is the perk tree. You gain a perk every time you level and you are able to put the point into any tree. But the amount of perks you have are limited, 81 being the highest level. This means that although you can become a master at every art it wont be effective because of the perk limitations. In previous TeS games this was not true, attributes and ranking up to apprentice, adept, expert, and master made you better in that skill along with leveling up the skill normally. In skyrim this isn't the case you only get a minor benefit from leveling the skills up, the main customization are the perks which you are limited to.
The perking system was a bad choice for a good game. Without the attributes and a good leveling system skyrim was really held back from being an even better game.
What does everyone else think?
Well, I miss attributes, but I don't recall a TES game with a good leveling system so not sure how to relate to that. Honestly I would have preferred that attributes leveled automatically based on what you did skill wise, as opposed to people hunting for multipliers and picking which attributes to raise first. Course even with that people would still be meta-gaming which skills they used to raise the attributes they wanted raised.
So, while I miss attributes, I can see why taking them out was done. Oddly enough, after 450+ hours, I don't miss them that much (though I still catch myself hopping down the road from time to time).
With the absence of attributes the perks are absolutely needed as they are now the new way to define a character. I do not want the perks to be automatic either (like OB). For example every character I have retired has had a very high Lockpicking score (80+). Why, because every character I play has to pick hundreds of locks. But I have never ever ever and never will select a Lockpicking perk (they are a total waste IMO). I instead put my perks on other things. So while I may retire two level 50 characters, and they both have very high Lockpicking skills, the two characters are completely different due to the perks I did select.
I'll be honest I was one of those that hated the new system before the game came out. But the more I play the game, even up to higher levels, I find that the current system is about the fairest TES has had. It is not perfect, and it is simplified, but it works well enough, which is more than what you can say about some other TES games.
