Mixtape gun evolution broken mechanic

The gun evolution from white to blue, blue to purple, purple to gold is not a good mechanic. It cancels what the player is doing (healing, shooting, etc) and anything that overrides what a player is doing is a broken mechanic, in the worst way. 

A much better alternative would be to replace the gun evolution with the legend upgrades in BR modes. Have mixtape help players learn to play legends better by using the same level ups.
