Map Completion Rewards Scaling?
I am not 100% sure, but I think the rewards are always of the level of the area itself. If they scaled to your level then no one would 100% a zone until they hit 80 so they could get a bunch of free high level gear.
I can say that I finished a 1-15 zone at level 80 and got level 26 items, and the 70-75 zone gave me level 71 exotics at 80. So it probably scales lower level areas a bit with your level to avoid ticking off anyone that outleveled the area they were 100%ing a bit before they finished completing it but it doesn’t scale enough to be abusable, and I think the higher level zones that have guaranteed exotics have the exotic’s level preset without any scaling (for instance every person I have seen link exotics from completing the Cursed Shore has linked one level 76 and one level 78).
When first we practice to deceive.
Most of the map completion reward armor/weapons that I have gotten were the mid-level or a bit lower for the zone, not scaled up or down for player level.
