Over the past months I've seen a bunch of people want custom weapons in Destiny. While I too think that it'll add alot of depth to the experience, the way they present it is often broken and would make every character a walking armament of overpowered perk sets. Here is what I suggest for custom weapons: 1. And this is an absolute must; custom weapons are exotic weapons or at least take up your exotic slot. This would prevent players from having a full armament of customized weapons that max out the potential of every weapon equipped. It also makes players consider what perks would be worthy of their exotic slot. 2. Custom weapons require two fully upgraded legendary weapons. One of the legendaries is dismantled and you are allowed to add two of its perks to the remaining legendary. The perks show up as additional choices under the existing talent tree of the remaining legendary. These perks cannot include damage boosts or damage types. You cannot use raid legendaries for custom weapons. 3. Give this role to the gunsmith. Banshee-44 needs work outside of ammo synths. [u]Debatable points[/u] 4. Additional cost of marks, glimmer, exotic shards, etc. for the gunsmith's services. The cost and grind of two fully upgraded legendaries may or may not be enough. 5. Progress of the remaining legendary, which becomes the new custom weapon, is reset. Because it wouldn't be Destiny if it weren't extra grindy. 6. Custom weapons must be made from two of the same type of weapon. This depends on how much better unique perks, such as the pulse rifle's headseeker, would be on other weapons. This would narrow the selection of perks readily available at a given time, but for the sake of balance it may be necessary. Or, unique weapon perks such as headseeker are only made available when customizing two of the same weapon.
