I personally think that the class system works well for both captain and skirmish. It just needs polish, and more variability with an addition of maybe one more perk. The load out system is cumbersome and would still just lead to a few default load outs, which doesn't really make that big of a change to the game. Taking your shoes off for a bit of a speed bonus? That's just ultimate micro managing, and most players will not want to go to those lengths. Sure, give the option once private servers come out, but otherwise? Keep the classes.
