The enemies would be harder to fight and kill. Making the cap higher to become über God Master of All, just makes you even to them and therefore not much of a challenge.
New Vegas does not have scaled enemies to do just that. To give you a challenge. Deathclaws and other creatures greater then your ability to kill. Becoming über God just takes that away, forcing the devs to add bigger enemies aka bigger bullet sponges.
Styles you do have valid points and i do take them into consideration as long as they do have better weapons and have a brain that will make me shot from cover sure ill accept that.
But me and my brother( he was the one who got me into fallout) agree that the way they did the perks was garbage thats one of the reasons why i want a level raise to 40
