Interesting idea, though it would be insanely strong for the start of any engagement when most players expect to be fully reloaded. The time to kill might go down drastically if it really lets you deal damage 3 times faster. It'd be a beast with the quick reload on ability use item too.
Simple concept for a cheap item that might be able to make up its cost over the course of a game. Lucky Break increases the chance of finding a pickup when you break a crate. Would probably have to be pretty cheap and increase the chance by a third at least to be much use. Still, would be cool...
