I unlocked my FSCS on friday night around Midnight or Saturday around 1 am something like that...For what it worth this was my path...
Artisian
Medic
Creature Handler
TKA (HOLO 1)
Scout (HOLO 2) ... I know lol
Brawler
Marksman
Entertainer
(HOLO 3) silent
Dancer
Squad Leader (unlocked FSCS)... I know lol
I had it pretty easy if you ask me...with the changes to the system coming I'm not sure this will help any of you or not...
Goodluck unlocking yours...
