I thought it was because we're not yet certain whether the gang'd be more practical as physical backup or as matrix assistance.
But anyway we would use them only when we need their help. on the day of the Job. - till then we have a lot of scouting to do and a Truck needs to be stolen.
Witch brings me to think, that we might steal the truck and Pulse could get helping on that and while Andromeda Works on it he could hack.
But Right now we all are prepared for the meet, but have started second-guessing it bit too late.
I think we should test the water first with the Gang, see what they agree on if they want to cooperate at all.
