OP10 Game Mode - Terrible Loot Drop rates and Dropping OP7, OP8 Gear

Currently farming for OP10 Gear before we start out on the new DLC. Having some trouble with your loot drop rates and LEVEL rates on these items, when and if they do drop. For example, we are farming for a Slag Lyudmila Sniper from Gettle in the Dust, and the drop rate seems to be awful!! When we can get the sniper to drop, they are consistently OP7 and OP8 even though we’re rolling around on OP10. Is this normal? Kind of feels like a waste of time grinding this out.
