i like your requirements d4rky. my only suggestion would be maybe add a medkit ribbon requirement for assault, resupply ribbon requirement for support and possibly a spot assist ribbon (from TUG-S/Pokeballs/MAV) or a spawn ribbon (from beacon). just a thought. this would make people play the classes to the fullest extent and utilize all of each classes abilities.
i think it would be cool to have mode specific medals within CAG. maybe like 250 flag capture/defends for Conquest. 250 MCOM arms/defuses for RUSH. 150 bomb plants for Obliteration (only 3 bomb sites per game). 500 flag capture/defends in Domination (since flags cap super fast). give them all large point values as well. it would encourage PTFOing and award those that do. just another thought.
