Adept Trials weapons are always on a hiding to nothing. Getting to the Lighthouse is probably the hardest thing to do in this game and only a certain % of the player base has the skill to get there. If they were a true representation of the skill needed to get them, they would be way to overpowered and thus giving already skilled players a even bigger edge on the rest of the community. As it stands I think the system works, snapshot is a useful perk and doesn't make the gun overpowered compared to its none adept counterpart. As for the different colour, it's basically bragging rights. Not my cup of tea but then again I'm just salty because I don't have a adept Doctrine of Passing.
