To explain better my point of view, since it seems too complex according to hena, my purpose is to give to a swarm as many D6 for spawning as the number of synapse in the swarm (tyrannid warriors count for 1 even if they are 3). In this way, you loose no D6 for spawning when you group synapse, only activation.
Now, I'm going to speak about the Queens!
- For the ants, ok it is true that some species (especially nomad species, like fireants) have several Queens, but it is very rare (less than 10 species among about 1000 different species on earth). It is equally true that you'll never see a queen on a battle field. So my example wasn't very relevant, because according to this fact, the limitation would be 0-0 ^^.
- For the bees, sometimes (very very rarely), some bee-keeper find beehive with two queens (never more). The mother and the daugther, but it is STRICTLY temporary. The daugther always quit very quicly the hive. A lot of studies have been made to create two-queen hives. It is purely artificial. The sting of the two queens is cut, they are put together in a box, alone, with no other bee. At the beginning, they figth together. After a moment, they eventually understand that they can't kill the other queen (it is a little bit a stupid animal, we speak about a bee ^^). After that, they will be able to work together and to create an hive with two queens. But in the nature you'll never find a beehive with really 2 queens.
According to bee-keepers who have practiced this manipulation, the balance of the social and biological functions of the colony is totally modified :
- Bees become very 'sweet'. - The reproduction instinct disapears (no daugther is created in order to create a new hive). - Bees loose theyr agressivity against other bees. - the hive finally accept 10 queens. - if one of the queens die, she is replaced by the hive.
Finally, I don't see the problem with the 0-1 limitation. Do you often take more than one dominatrix? Moreover, lictor formations have already a limitation of 0-2.
