Gottcha. Then I would agree with that. Any Enclave survivors from DC/Chicago are in absolutely no position to emerge as a powerful faction again (or at the most for a very very long time). The only way I could see the Enclave taking an active role in domination again is if a Barnaky-MWBOS/Enclave alliance occured, which is at least somewhat plausible.
Which basically mean the Enclave are absorbed byt eth MWBoS
