So this is for players who want to max their levels. Some may not be interested in this but you don't have to use this feature. It is a completely optional decision for the player.
I am definitely looking forward to this because I would always plan what perks i need to spend to get what i want. But now i don't have to!

Though it will take longer to level those skills to get a perk, it will be easier with the amount of magicka, health and stamina you have and what kind of weapon you have as well.
So i am pretty excited for this.
