How would that balance the game? People are already finding it a bit too easy after hitting level 25.
The word "balance" generally implies that it will make the game enough of a challenge, while still keeping it fun. Adding more perks would just make the game easier.
Let's see... how WOULD it balance the game?
First off, it isn't overpowered. From level 1-81, you can max MAYBE 3 and a half classes by getting every perk affiliated with that class. With 2 perk points, there's a substantial increase, but without being overpowered.
I could max Heavy Armor, Destruction, and Blocking with full perk points, which is sort of a good 'goal' to have when using a Spell-Sword character. Otherwise, I wouldn't be able to, which would limit me.
I know spending points on things like Blacksmithing, and Lockpicking would be less helpful than that of spending the points on combat-related inquiries, but WHO doesn't like variety in a video game?
I don't want my character to be full-blown combat-oriented. I want my character to have a little variety with the other skills you can do ingame. The only problem is that if I DO that sort of thing, then I ruin my combat-experience.
Let's face it. It's UNDERpowered, and maybe that alone is an understatement. I want to skill in the game, but I also don't want to get torn apart by enemies. There's not a lot of variety that Bethesda is offering.
Now you explain to me. Unless you are a stubborn and die-hard combat person, then what part of what I just suggested makes the game too easy? If it's too easy for you, then it generally implies that you only care about combat, which can't make a valid counter-argument. There's too much variety.
