The 2 is scaling, like the ennemy does
But the scaling of ennemies weapons is really weak because Tennos have thousands of HP, so they can't hit 20K or they would OS frames
There's a scaling, but it's lazy and badly done, they just copy-pasted the actual ennemy scaling, and as story told many times, it's S#&$ in all of it's aspects.
And I see "Range for GOL please" everywhere, range alone would not save this ability
Even with 11(!!) guns, you start killing ennemies really slowly when they're past lvl 60, better go for melee then.
It need to be changed, from scratch
