I think that there should be perks, but clearly the system in Oblivion wasn't as fun as it looked on paper. I would like if there were multiple ways to learn perks (sort of how you can get perks in New Vegas just by doing actions, like killing insects), such as reading a rare book, learning from a wise master, hitting a certain attribute threshold (like 70 strength + 70 agility or some such combination of attributes or skills).
I agree. And since skills are further reduced, perks will allow for better customization, if there are a lot of them, and also is some of them can negatively impact other skills/weapon types. Perks will have to pick up the slack, but hopefully in a fun and interesting way.
