For me, last one. Or if you really want to be together, run them toward each other. I try my best to not release until all my alts are dead. It makes sure if a GY gets taken in the meantime, they all end up together. For WSG and such, if it is just 1, I run the 1 guy (click to move goes a LONG way) to my team, if it is 2, I meet them up together (each go half way). If I am on a mission (carrying flag, guarding flag, etc), I always do mission first and ignore the alts until I am either all dead or mission done.
