I've been running ABT with FCS for 4 games now. Not many. There have been times when I've missed AC but the number of times I have been able to roll 4-5 red dice with a target lock while stressed more than made up for it. Add Solo crew...... it feels like cheating.
Might be the wrong forum for this question but does this work?
Roll for ABT get a focus and a blank
Use TL to reroll the blank and get what ever.
FCS gives you a TL which you can then Solo the focus.
Yeah doesn't sound right.
