Bud, firstly, i know it's a stupid system, but you have got too much old gear on. You have 1 old gun and a piece of old armour on. Also, you have 2 exotics that are not featured. This, unfortunately, will give you a smaller multiplier. Which ends in a lower score and worse gear. Restoration can be tricky to keep up unless you're dialled in, so I'd swap to the healing grenade you'll benefit more from it, trust me. You could even try a Prismatic devour build they work wonders. You'll learn the missions i portal after a while. They're really not that bad. Even on Grandmaster, believe it or not. I know getaway artists are not featured, but they are goated for constant devour and healing. Maybe try making that build if you have them.
