Now in my opinion it doesn't need too much of a buff, after all it is a primary shotgun. However the one thing I think could make the weapon feel more exotic would be an increase on ammo size.
Considering how slow the reload speed is an increase from 5 shots per mag to 7 shots per mag would make the weapon feel more exotic. Or perhaps in increase in the amount of reserve ammo. I know it is a shotgun but seriously Bungie we expect our primaries to hold a lot of ammo and my experience with the Universal Remote (as well as the No Land Beyond) is that it needs more ammo.
Well, those are my opinions on how the Universal Remote could be improved upon.

Give it an Impact buff due to it's low RoF, Give it a high base range, replace Crowd Control with Shot Package so you can take advantage of the Universal Remote perk for bonus precision damage
