Picture in picture scope is harder to use than in normal mode! The difference between both modes is huge enough to make the game unbalanced If players can mix bouth modes in online gameplay.
Only way I see to make things more balance is to blurry the nomal mode yet more. Normal is not blurry enough to equalize the gameplay!
As the pic-in-pic scope is also very blurry(is that a bug?), I think the game LOD could be diminished more in non scoped areas to make performance yet greater if that's possible,but that's just an idea! The overall performance is the best till now, I can't complain.
