i find i only use them in heavy combat when i am already kicking but its jsut to finsh.saying that if you synch i think its 5 or 6 and replay any mission you have a cheat for exactly this option so will not be hard ih the long run to add.
saying this calibre PLEASE for the love of god add an option to unlock all weapons/armor and more important DE EQUIP ARMOR!!! because of the trainer bug i can't unlock all items for my achivments (before you ask going back a mission does not fix issue)

I mainly use them for full sync on missions where you can't be detected while escorting, or following, or whatnot.
