2 for sure.
@mesterKG I think it's that freedom that kills the team play element - Everyone can equip to any combination, which lessens the need to rely on your teammates; it feels like it encourages solo play rather than a type of team coordination.
Playing Support in previous titles, I've never really thought in terms of mini-objectives for resupplying unless my squad was attempting to do something specific: "I have a machine gun and unlimited ammo with my crate, but I'll need to rely on a medic or two if I get into a tough spot Hey, while I'm running by, that recon sniper looks like he could use some bullets! I'll drop a crate on the way to my new position". That said, if I needed a medic, I could easily spot one by using the class based system; there's currently no way to see who has a medpack to render aid.
WIth the specialist system, I hardly saw an ammo or med box at all - I presume, based on some feedback I was reading in teh open beta forums, that everyone was equipping a combination of the armoured plates and rockets, because they could and it helped them score kills (not necessarily coordinating or pushing for an objective). I was also able to think, "Hey, I want to play as a sniper but I'll run out of ammo, so I'll have the specialist with a grapplingf hook, sniper rifle and an ammo box, that way I'll be almost entirely self-sufficient!".
In previous titles, I had people run up to me and request ammo - I played a part in their success because my class allowed it and they knew I had ammo, not because I necessarily actively chose to be a team player (though I'm all for playing the objective). That team based mindset was never realised in-game with this specialist based system. That said, yes, there were supports that ran around without ammo resupplies of any type, and it was frustrating to deal with :D
