My explanation for the different power levels (and CGI models) There are many "classes" of Insecticons. The two we saw previously were "warrior class" and the bulk of the swarm we saw in "Armada" were "worker class". Members of the "warrior class" are far better equipped with armor and redundant systems to give them far better endurance, at the cost of having very limited mental capacity. They are the vanguards and defenders of the hive. Most of the swarm we saw today were "Worker class" insecticons who make up the majority of the hive. They have less armor and endurance but have greater mental ability as well as the ability to breed faster. The one we saw in "Tunnel Vision" was also a "warrior". Thoughts?
