I would like Fallout 4 to take a page out of skyrims enchanting system and be able to mod your gear with legendary stats.

• like skyrim you should require to unlock the legendary stat by either obtaining it first or scrapping it
• the armorer blacksmith science etc perks should require maxing out so you cant do it to early in the game or create another seperate perk that requires you to be lvl 40-50 to unclock it
• should require significant materials to mod them

or what you could do is build your own legend with your gear by having a legendary level system which allows your gear to gain exp with evey kill you do with weapons and how much damage you take with your armor. Once it has reached the legendary level take it to a weapon/armor mod station and mod it with a stat that you have discovered.

if somethingl ike this were to be implemented I would like it as a patch or free dlc rather than a paid dlc

Craft Mods for stat boosts also.

It's great that mods usually pop up but traditionally they are not well balanced and over do it on Stats and Abilities.
