Dev's Intentions for Each Class

[Palerion]

I've been wondering for a while what the devs are planning to do in terms of the direction of each class.

For instance, is Light Assault intended to be a sneaky class or a speedy flying skirmisher? I'm aware that on the test server they have made the jetpack louder, so I'm thinking they're leaning towards the skirmisher, but I could be wrong.

Is the Combat Medic intended to stay strictly as a support class, or will it eventually become more anti-infantry?

Is Heavy Assault going to remain the best infantry-killer and (excluding engineers with their new AV-turrets) vehicle killer?

Is the Infiltrator going to stay a simple sniper, as it seems to be right now, or evolve into an assassin and actual base-infiltration class?

Only class I don't really have any questions about is the engineer. It seems to have a pretty defined role both in combat and support.

While none of you may have actual answers, I'm just wondering if we have any ideas. It completely baffles me as to what they plan to do with the classes in this game. Things seem very subject to change and, right now, many of the classes seem unfinished and incomplete in their roles.

EDIT: not sure if "new player questions" was the appropriate place to post this. My apologies if this is in the wrong section.
