Is there really any point to having 40 levels of % luck on every colour of drum? I can cap on drums without much trouble at 1% and still be swimming in packages, first upgrade I've seen in the game that seems completely useless.
"Red Luck" is amazing due to a lot of different things, mainly the "Build Red Reservoir" idea and the fact that it can be kept.
"Orange Luck" in small amounts can be good for speed, as well as a very small amount of the next two.
But I can agree that later lucks (like "Blue Luck") are nigh useless in the current game state. Make such to get high amounts of "Red Luck," but you can definitely skip out of the others if you'd like.
