As it should. Add new perks? Give me a perk reset or ability to level past 81.
Didn't the fall out series do this every time they added new perks? Raising the level cap.
Fallout's gameplay differs greatly from Skyrim. In Fallout, theres a need for an increase in level cap. Though IMO, 50 in fallout was a bit much. 30 felt perfect to me.
There's no need for a level increase in Skyrim. The addition of new perks IMO is fine, as most players don't spend perk points on skills they don't use.
