User blog comment:Jimeee/Skyrim 1.9 beta update adds Legendary difficulty and raises level cap (Updated Apr 8th)/@comment-5077844-20130514140615

So just to get this straight, it's like this with the perks: As soon as you got one tree to 100 you can set it back to 15, level it up again, and therefore not only be able to invest the previous points again, but also to use any new acheived perk points wherever else you please?
