I am wondering the same thing....I like to mix it up a lot in combat, so I am adding perks to one-handed, two-handed, destruction, conjuration, restoration, blocking, archery.....is that going to screw me when I am high-level but not highly specialized?? Basically I want to add perks to almost every skill tree....maybe not the stealth oriented perks so much.
Exactly. Think of it this way. You use archery as your sole combat skill, and you kill 100 enemies. That's 100 "points" that goes into archery skill. However, if you use destruction magic, archery, and one-handed weapons and kill 100 people with those, that's about 33 "points" that goes into each of those three skills. You end up being one-third as powerful in each skill than if you focused on just one of them. At least I think that's how it works. That's what this thread is for, to try to clarify this.
