It's okay McB, I aint gonna judge. I get what you're saying. The term "Legendary" kinda makes it sound like something REALLY epic is gonna happen once we swap that skill set upwards. Turns out, it really goes downwards.
From what I've read (over at Beth) the people who like the idea like it because they can keep leveling their characters upward, without having to take on perks that have nothing to do with their RP. In other words, if they have a gallant knight who maxes perks in all the 'gallant knight' sort of perks (let's say two-handed, heavy armor, maybe some spells like Alteration and Restoration) the player wont' have to take Sneak or Pickpocket perks just to keep leveling upwards.
It's a cheap fix, but at least it is a fix. I have yet to get this far with
any of my characters, so far as leveling goes..
My spellsword who made it into the 50s decided to retire, for instance.
