So that's a great point, I didn't catch that in the 1.5 FAQ. I'll have to update my Gromoz build. One interesting thing I noticed as well was that it seems in the Outcast campaign you actually can take up to 9 specialties as you start with 1 and gain 8 more across the missions. See page 13 of the outcast campaign. This seems to also be similar in Revenant.
A side question for Raoul. How do you feel about his Specialist Operative cards? His First Aid card feels kind of weak and low impact? Does Refractorise(?) allow you to add the to Interacting with Consoles via a Hacking Device? Is it a Hacking Roll?
Interaction roll is not a Hacking Roll by default. If you have a Hacking Device you may use a Hacking Roll, if not - you use And since Raoul is not a Hacker you can only get him Defensive Hacking device
