It seems to me that for any set number of minions, the more separate groups you bunch them into, the more dangerous they are for players to face. I have a number of reasons in mind:
(1) Action economy: Four groups of three minions get twice as many actions/maneuvers as two groups of six.
(2) The dice: The system favors rolling more dice over upgrading dice. Adding minions to a group upgrades dice until you reach a certain point; adding more groups always adds more dice.
(3) Generally low defense scores: Piggybacking off #2, an average PC has defense 1 and might upgrade incoming attacks once or twice. A single stormtrooper will hit that target about 45% of the time. That isn't bad odds.
(4) Soak: A minion group only applies its soak once to each hit. So 16 damage against a stormtrooper group will kill two stormtroopers. Against individual stormtroopers, it takes 11 damage per man to kill them.
There are a few factors that run counter to these (like PCs with incredibly high soak, if your group has one of those) but overall it seems pretty clear. Am I missing something?
