open world and exploration are definitely the primary selling points. but, in general, i assume that people on this forum are well beyond those as 'selling points.'
i know it is for me. it's expected. it's required. it's a given.
regardless of that discussion of opinion, the perk system and leveling what you use are the 2 major 'selling points', attributes, whatever word you'd like, of skyrim when compared to morrowind and oblivion.
and, for such a huge part of what makes skyrim different to be so flawed, yet, accepted, doesn't work with me.
Idk... The parts of the Perk system that you are seeing as flaws, I just don't see them that way. I see it as a logical course of progression of the character.
You start out knowing a little bit of nothing about everything. But as you level and spend Perk points, even when just working through the "worthless" Perks, you eventually become a Master at one or two things while being good at a lot of other things.
I think it's just a part of the "learning curve".
