I don't see what the commotion is about. Stormtroopers do nothing but shoot guns and get shot. They never say anything of note, do anything of note,
and their black-clad leaders, who are enamored by the Dark Side, don't seem to give a hoot in hell how many of them are killed so long as they do their elitist bidding.
Sounds like putting black dudes in the suits is a logical, almost inevitable move.
