Now if you're talking about your own personal feelings about how the way the game should have been done then that's extremely subjective and not a fair way to judge a game.
The question was "would you still have bought it" after having played and seen the game. That's a personal decision, and thus it is absolutely valid to judge a game based on flaws that create perceived imperfections within the game. Should the game be judged solely on how well the engine runs, I mean, come on, at some point a judgment has to be made about the gameplay itself . . .
Flaw: the Impact perk + Enchanting allows a Destruction mage, with no other skills except for Enchanting, to stunlock anything, indefinitely. Without ever running out of mana or fearing reprisal. That is a major flaw, whether it is seen as one of those "always has been easily obtained divinity within TES games" or not, it's still a huge flaw. There are plenty, but I was only naming one of the most glaring (to my personal gameplay.)
