I find I commonly want to generate a random event for whatever reason (currently weapon rarity/stats)

Haveing something like "switch in int" but where there is a defualt it goes to in "all other"
And the rest based on a 0-1 float (with inputs so could used variables setting up things like player "luck" or curses etc) that would generate a random float and use one based on the probability.

Just be nice to have it as a basic BP thing rather than building them or creating macro etc due to how often things like this are used.
