No.The way I see it is if they made the gun nonfunctional until every mod slot was filled then you all would be happy.
That’s the way the old system worked. You found parts and the gun wouldn’t function until all the parts were included.
Now you can shoot the gun for base damage while you assemble it. But if they took that out and made it like A16 so that you could only use the gun once fully assembled you would see your differences in damage and power between purple blue green yellow orange and tan quality tiers.
'♥♥♥♥ i better dye my gun pink so it actually works'.
The mod system is always going to be far inferior:
We went from a gun being a collection of unique individual parts affecting a number of diffrent stats to dying it an obnoxious colour for more damage.
Explain it away all you want, one was a complex and deep system and the new one one is 'hurr durr my gun is painted green so it hurts more'.
