I use these, separately or together, when I want to make a minion group almost as dangerous as an equal-sized group of Rivals without slowing down the game by giving them all separate initiative slots. Just throwing this out there in case others wanted to achieve a similar effect with their minions.
Elite Minions: Skill ranks for this minion group are capped at 7 rather than 5.
Coordinated Attacks: This minion group's attacks have the Linked quality, equal to the number of minions in the group beyond 1.
