No, using the console command setav [actor value code for skill] 15 simply resets the skill to 15 just as the Legendary Skills option does. The perk point restoration feature can't be duplicated but using the removeperk and addperk commands on a point for point basis has the same effect. You're still leveling the same way as you would with the Legendary Skills feature, i.e. by using the skill. I say limited because with the Legendary Skill feature you don't get to pick how low you reset your skill. I can reset one-handed to 75 so I don't lose a lot of damage and continue to level the skill and my character levels with the console command and repeat as needed to keep leveling.You say 'limited', I say 'without the need of hax'. It lets you level naturally instead of adding points through consol commands.
