I think if we want to give a bit of life on the infiltrator class without too much coding(?), maybe the best way would be to give ALL infiltrator actions a 'leverage' as have the adventurers: From -Maximum stealth, Minimum risk- to -Very Aggressive, Maximum risk-
This way the infiltrators would begin to work without too much training... of course as less risk, less chances of success... but less chances to be caught too!
