NowGamer: Black Ops 2's customisable Pick 10 loadout system has over 500,000 combinations - Treyarch reveals how it is balancing every possibility.
probably like every other call of duty....they don't balance it what so ever.
Call of duty is beyond balancing. There will always be overpowered guns in all the games and stupid combinations. Just have to look at the competitive "esports" scene to see just how much stuff gets banned because of the balance.
For something like this, it will obviously be very difficult to balance because if people can pick and choose what they want to use or not to use, then it is up to them to know what they are opting out for. If they complain about something (if it isn't something broken) then it's their fault and they are the ones to blame for using something they either can't use for the way it is set up or for using less stuff against people who may have their own defining set-ups with more gear. As long as things aren't out of place and one thing isn't overkill compared to everything else it should all work out.
