Allow you to switch between characters on a command post during game as the objectives change as you progress because you may need to become from a solider to an operative, and if you spent all your credits to buff up the solider aspect then your screwed if you have to change.
Plus this would give creating characters a meaning OR they could simply give us more levels so one character can change from a solider- medic with no problem what-so-ever.
What do you guys think?
