Might be nice to have the option to vote on a rule to set no duplicate classes in a game. There are 6 spots and 6 classes its a race from the start of the match to pick your favorite and in theory should balance teams the way the game was intended. No more situations where the other team is waiting to see what your team is selecting before the match starts. Just get in and grab what you can while its available and go. Trade class system could be setup during repawn time if both parties are willing. The other thing is it might bring a little more positive communication to the game so the lobby is actually used to plan class selection and a buddy system for people to trade classes. Might actually for some people to get out of their comfort zone and play a class they haven't mastered so someone else can practice without being totally destroyed in the battlefield.
