At first when I played the beta I seen 4 classes and I was really bummed out, but honestly they did a good thing moving to 4. Each class does feel VASTLY different, like you are mant for a certain job and another class might be able to fill that role partially, but not like the perfect class would.
Assault is really the only one I would say is a bit more open ended and doesn't have a specific role, but 2 or 3 roles. Since with a Assault Rifle they get a Grenade launcher than can be Smoke, Grenades, or another thing I can't remember. They can provide good cover, and the Ammo regen is a bonus if you can live through your clips. But with a shotgun that kit does a complete 360, and I tend to like it more with a shotty. I'm not much for Snipers, and once they get Mortar Strike, there is no use for C4, heck there really isn't a ton of use for them having C4 anyways. So when you use a Shotty as Assault you now get to use that C4 in close quarters and you can regen C4 ammo, it works very well.
But beyond that one class, Medic, Engineer, Sniper, those are pretty obvious on your goals. Engineers guns are good, but any open area of map and you might as well be dead without a vehicle, those weapons are great in town, especially since no main kit has shot guns now. If you round a corner against an Engineer kit, expect to die most likely because they will put a whole clip into your corpse faster than you can say "dammit".
And now that Medics have LMG, all I have to say is "oh my jesus", I love this kit, if you like feeling like a badass mofo, nothing is cooler than this kit. And there is honestly a lot of bad medics, it's rare to get revived, but games I was in I would average around 20 - 30 revives. There times when a medic will capture that crate or flag and without him, it just wouldn't be possible. I would just sit in a corner toss health packs down, and raises my friends corpses, they would die again, but when the bullets can't reach me, that crate or flag goes down, then I die, but served that purpose.
And Snipers, well ranged, doesn't get much more simple than that. So picking your styles with the kits narrowed down to 4, it won't take long for you to feel out what you really like and you really don't like.

Maybe if they don't respond by email by mid day tomorrow call them, and tell them you you'd just rather cancel your pre-order and go through someone else if they can't resolve it.
