Idea for next Battlefield

This suggestion is huge change back to old days of playing Battlefield and FPS:es with established classes. I do enjoy roleplaying aspect of games with distinguishable class rosters. It helps building readability, dedication, focus, management and co-operation. What I do wish is that so called "sub-class/kit"-thinking wouldn't dissolve idea of selecting a role and playing fullest of it. I also hope that whole loadout would have carefully chosen equipment options there.

So, here's recommendation for a backbone of what I do wish to come true.

• Medic: His job is keeping team mates alive and healthy in battle condition. He aids team via medical supplies, combat boosts and revival item. Unchangeable locked gadget slot would be a defibrillator.
