Ok so I was thinking about how we could over hall or improve the mods system in Destiny 2. After thinking about it we have a natural progression with how the mods could work, we have rare and legendary mods so how about exotic mods. Firstly what would an exotic mod do? Well with the exception of trials and raid weapons all the guns in the game have 1 tier 1 perk and 2 tier 2 perks. A tier 1 perk could be anything from kill clip to full auto to clusterbombs. A tier 2 perk would be armour piercing rounds or high calibre rounds. So what if you could get the schematic to drop for an exotic mod from a raid chest (or other endgame activity) Each schematic grants a tier 1 perk to a weapon, though not every exotic mod can be applied to every weapon. (sorry no full auto hand cannons) To convert a schematic into an exotic perk you need to spend 25 legendary shards 10 weapon parts and 5 tier 1 perk weapon cores (i'll come up with a better name eventually) What are tier 1 perk weapon cores? Well when you dismantle a weapon with dragonfly on it you get a dragonfly weapon core. So you will need to hunt down 5 weapons with dragonfly on the and dismantle them to get a 5 dragonfly weapon cores. This would means multiple drops of the same weapon become useful. Once you have unlocked an exotic perk it would go into the vault under exotics and can be re purchased by spending the same materials again allowing you to put dragonfly for example on multiple weapons. This could help increase the endgame grind, as you would need to repeatedly farm the raid/trials to get the schematics to drop and could allow some pretty awesome weapon rolls such as a scout rifle with triple tap and full auto or a rocket launcher with cluster bombs and kill clip. Anyways just one of the ideas i've had what do you guys think?
